VOLTRX Electric Shaker Bottle - VortexBoost Portable USB C Rechargeable Protein Shake Mixer, Shaker Cups for Protein Shakes, BPA Free, Waterproof, Colored Light Base, 24 oz (Power Blue)

I purchased this protein powder mixer in January 2025 to take on a cruise as I have a specific diet with low saturated fats. I mix custom vegan protein shakes every morning to get started. I bought this mixer because I liked the USB-C charging capability and lightweight factor to carry in my backpack. I have to tell you this mixer did not disappoint. I used it every day on the cruise to make my drinks in the morning and it washes out very easy. You just rinse it out air dry no problem. I liked it so much that when I got back, I stopped using my Ninja blender to make my protein shakes because I liked this mixer better. I liked it because of the simplicity and the ease to clean not to mention how portable and compact it is. It’s never failed once and the charging unit holds a charge for a long time. I only charge it maybe once a week. I am absolutely thrilled with this product and I have read that the customer service support is outstanding however I’ve never had to use it yet. If this ever breaks down, I am definitely buying another one. In fact, I might buy a couple more just to keep in case they somehow go out of stock. This is one of my most prized devices that I use every day outside my iPhone you can’t go wrong with this product five stars. UPDATE: 9/10/2025 Still going strong. Use it everyday it’s never failed. It travels around with me. I just bought another one in white cause it’s easier to see through. I will be giving these as gifts at Christmas time. Love this blender.

Great product with a variety of beautiful colors! Ive bought a few of these now and I continue to be impressed. When I had a issue with one of them, I reached out to customer support and they immediately helped me. They were extremely kind, fast, and understanding, which reassured me and further strengthened my loyalty to both the product and the brand. The blender itself works well and blends smoothly without clumps and is perfect for protein shakes, pre-workout mixes, smoothies, and superfood blends. Its portable and convenient so i dont need to drag around a large traditional blender since the bottle itself is the blender which saves time and reduces the amount of time and stress we all know can come with cleanup especially if you have a busy schedule. I haven't had any leakage issues so id say the seal is nice and tight and the build quality feels sturdy. The battery's rechargeable and lasts a good but not great amount of time between charges but honestly a minor issue as you could just pop onto one while youre doing literally anything since it doesn't take long plus its a nice compact size so you could easily throw it in a gym bag, take to the office, or even go traveling with it which I tend to do. This is a must-have for gym rats, busy professionals, or honestly just anyone who wants a reliable portable blender thats still stylish and easier to clean especially with all the pieces and nooks and crannies you have to go through cleaning in tradition blenders.

Bottle has been working great so far. I've been using it almost every day since I got it and it's been holding up great. Feels nice and solid and it has a little loop if you want to attach it to your bag or something. I think this one is more expensive than some other options, but cheaper ones tend to break and feel cheap, so you definitely get what you pay for. I recommend paying a few extra bucks to get this one, which is better quality.

UPDATE: OK, so the company reached out to me and reported that their response to me was delayed due to a fault in their system on their end. The person I worked with was more than fair in their solution, and ultimately replaced the original cup I had which was leaking. So I have raised the review from 3 stars to 5 because of the following -Once the company reached out, their customer service was excellent and they got a replacement product out QUICK. -The replacement product worked as expected (ie, doesn't leak.) -The mixing really does work super well WHEN MIXING PER THEIR INSTRUCTIONS. I'll point out that the difference between "mason jar" quality mixing and "it really doesn't need a mixing ball because there's no clumps left" is whether you are adding water and then protein powder (which I was already doing), and holding the cup vertically when mixing (which I was not previously doing). -All of the positive things from the review below remain, including being super easy to clean, nice wide mouth to pour powder in, feels well made, etc etc etc. All in all, this is my first mixer cup (so you can take that into context as well), but I am glad that I purchased this as it totally satisfied my desire to have something simple/easy to clean, quiet, and effective for mixing protein powder. Original review below with updated edits in brackets: As a bit of context for this review, this is my first shaker bottle. I exercise from home, so I don't need to travel with it, and I also exercise before anybody else is awake in the house, and didn't want something noisy. Previously, I was using a mason jar w/o a mixer to mix a whey blend protein powder. I don't have a ton of experience with protein powders at this point, but do know that this tends to clump more than some others I've tried. I wanted to try a mixer bottle that had a wider mouth, but didn't want to mess with a widget inside that needed to be cleaned. I'm lazy like that. So as I provide a narrative summary for this review I will be outlining my thoughts on the "about this item" bullet points for this item, and I am generally going to be comparing this to a standard, run of the mill mason jar. In reverse order: Leak proof guarantee. [the company eventually reached out and send a proper product that doesn't leak, so the remainder of this becomes for history only] This seems to be faulty on two notes. First, yes, it does leak (or at least mine does). That's the first thing I noticed about this product, and I initially thought I was missing a gasket, but I see now that Helimix claims that a gasket is not needed. Well, I can't say that to be true based on the product I was sent. I did reach out to the company via the channels suggested, and haven't heard back (it's been almost a week) [it ultimately took 8 days for them to reach out to me, but they stated they didn't get the original message]. I realize this can take time, but Amazon has already sent a followup email asking whether my problem has been resolved, and as I haven't heard from Helimix, it hasn't. So I wouldn't say it's leak free, and I wouldn't say that they are making sure that they are resolving issues (or at least if they will, they haven't yet). At this point I'm just trying to tighten it as much as I can (much more than I would expect that I'd need to) and sort of hoping for the best. This does help, though it makes me wonder whether there will be longevity of the lid. I will say that the amount of tightening necessary to reduce leaking makes it hard to unscrew, as the cap doesn't have any traction on the outside for grip. In fairness, after about a month of frequent use, the mason jar might have leaked twice. But so far, it seems that the mason jar edges out the helimix for this. Durable and easy to clean. I would say this is true. The product seems sturdy throughout, and while I haven't stress tested it in any meaningful way (aside from VERY firm tightening/untightening), it seems like it won't be falling apart any time soon. It does seem easy to clean as well. I don't travel with this cup, so I tend to rinse it right away and I haven't noticed any areas where powder tends to clump that I can't get to when it comes to cleaning (more to come on that). Before ordering I had some concerns that the powder would get caught in the lid, however the inside of the lid is domed and there's nowhere for the powder to get caught there, and the mouthpiece is large enough to clean inside so there's no issues there. I like the very wide mouth, as I can fit my hand to the bottom with a washcloth. If the mason jar I have were wide mouthed, I think it would potentially be a draw for various reasons, but I like how the helimix is big where it needs to be to make cleaning easy vs the "standard mouth" mason that I can't fit my hand into. Odor Resistant. I can't speak to this. As stated, I wash (or at least rinse) this immediately after use, so I don't really give it a chance to sit and absorb. It doesn't smell yet, but it's only been about a week. The mason jar didn't smell either. So a tie I guess. Superior Supplement Mixing. [having a product that seals correctly AND me mixing correctly, ie vertically, made all the difference... and yes, it mixes beautifully! The design of this cup really is clever and effective!] OK, this is a tricky area to speak on. In the packaging itself there aren't any instructions for use, though one wouldn't expect it needs to be any more complicated than "throw in the stuff, close and shake." I do know from limited experience that it's best to add the water THEN the powder, so I've been doing that. Now somewhere online it also suggests to shake the cup VERTICALLY, as this allows the shape of the cup do whatever the shape of the cup is supposed to do. Unfortunately, I haven't yet tested it in that way, as I have some real concerns about where the contents of the cup will end up if I do that. Instead, I've been shaking it downward into the sink, so at least I'm controlling where leaks go. So if I'm not taking advantage of the "technology" of the cup by shaking it correctly, it's a bit hard to tell whether I can fairly assess it's ability to mix. If shaking it vertically was also super important, I kind of wish that bit of information was clearly communicated inside or on the packaging rather than only somewhere online. That said, my inclination is to say that it "probably" does a better job than the mason jar... maybe? In both cases, it involves some shaking, some looking into the cup/jar to see whether I can see chunks, some more shaking, and so forth. In the end, some days there's a chunk left over, and some days there aren't. Sometimes there's a little unmixed powder hiding in the mouthpiece, and sometimes it comes out totally clean. I haven't really figured out the magic of consistent and completely blended results yet. I feel like it maybe takes less shakes with the Helimix, but I have to say that my experience of shaking them are different as I sort of walk around and shake the mason jar absentmindedly, and I shake the helimix rather purposefully into the sink as I watch for leaking. Maybe a slight edge to the helimix, but if I'm shaking it "wrong" due to shaking it upside down into the sink, then maybe it's not a fair comparison. No shaking accessories needed. [True! When tested with a whey protein isolate, as well as a whey protein isolate blend, no blender ball or "excessive shaking" is required to get a completely mixed shake.] As a stickler for the word "need," I'd argue this is true. It isn't NECESSARY, and wasn't in the mason jar either. They both mix the contents without a widget. If it's not mixed, just keep shaking. Not much to say here, as neither thing needs one, or at least they both function about the same without one. So pros and cons... [With a proper/non-leaking cup, I have to say that for me it's all pros! Absolutely an upgrade from a mason jar. So if it leaks, contact the company, and when you shake it, make sure it's vertically as this totally matters!] The Helimix seems well made, mixes well enough I guess (though my ability to use the product as they recommend it is hindered by the leaking), I love the wide mouth both for pouring mix in and access for cleaning, and it IS easy to clean (which was one of my main concerns before purchase). That said, the fact that it leaks is disappointing, especially since it's guaranteed not to, and more so when coupled with lack of outreach from the company to address my concerns after I've inquired for help with this issue. I'm hopeful that the company will reach out at some point and either tell me what I'm doing wrong (do there need to be tips/tricks for screwing a cap on?), or that I have a faulty product. If nobody outreaches however, I may end up trying to return/refund this and just buy a wide mouth mason jar.

Ürünü kullandıkça özellikle antrenman sonrasında çok kolaylık sağlaması şarjı da iyi gitmesi çabası tavsiye ederim mobil olarak kullanımı çok iyi benim için kurtarıcı oldu diyebilirim ...

Uszkodzona sztuka - brak możliwości zwrotu przez "łatwopalne ciecze w produkcie"

This is a great piece of kit for people who drink protein shakes. It makes taking protein shakes anywhere really easy. Just add water and press the button and you get a properly blended protein shake without the lumps you get from manual shaking. I bought mine just over 10 months ago and I can also confirm that customer service were great when it stopped working. The motor was fine but stopped spinning the mixer. Voltrx replaced the item immediately - no quibbles - although I'd contacted them to ask them how to fix the problem not to replace it. They give a 12 month warranty and stand by it.

Great mixer bottle. My third buy. Convenient for mixing your supplements after gym.

Heel handig dat de onderkant loskomt en goede indicatoren met licht. Batterij gaat lang mee, shaker is vrij krachtig (beetje dreft en hij maakt zichzelf schoon) en als je hem wast kan je de elektrische gedeelte er af halen. Enige minpunt vind ik dat er geen dop voor de usb c poort is. Als je perongeluk toch wel dat hele ding onder de kraan doet kan er potentieel een kortsluiting komen.
