Genteen Blender Bottles, Protein Shaker Bottle for Protein Mixes USB-Rechargeable Powerful Electric Shaker Bottles includes Supplement Storage - BPA Free | 20 oz Cup (Black)

The media could not be loaded.  I will not be using this shaker for protein mix, but instead I thought this was the perfect gadget to get, to finally enjoy some good homemade milkshakes, and I wasn’t wrong 😁The device is very simple to use, without any complicated steps to do prior use. Just give it a full recharge, fill it up with what ever cold items you want to mix, press and hold the power button, et voilà, done.Button functions are as follow:- Press and hold the power button for a few seconds = shaker starts spinning.- Press once the power button to stop the device.Points I really liked with this shaker:- It uses USB-C for charging, and last a good hour of use afterward.- The final result is indeed lumps-free.- Love the fact they had blue as color choices.- Makes milkshakes “foamy” and delicious.- Will come with a cleaning sponge on a stick.Keep in mind that, even if it’s safe to rinse it under running water, this shaker should be hands washed only, and not placed in the dishwasher.

It's awesome not to have to sit and shake or stir to death my protein drinks. An excellent time saver and great value for the money. It charges quickly, keeps the charge for an excellent amount of time. It's easy to use, just unscrew the lid add your contents and push a button. It's just as easy to clean and even came with it's own bottle sponge for just that task. This one also came with a little travel bottle to take extra additive with me instead of lugging the large bottle it comes in. The top is easy to drink from and has a rubber stopper to properly seal the opening preventing any contamination or spilling or spoilage if the contents and allowing for the temporary storage of your drink. I highly recommend this item.

The only way to get it to turn off is to plug it up to the charging cord. Not today, it won’t turn on. I tried changing it & the red charging light is on despite it not being hooked up to the charger. I have reached out to the seller as well as Amazon and I haven’t heard anything yet. I try not to leave negative reviews but the seller is unresponsive and the product isn’t the best quality. I’ve had this since March 8th. It’s June 21st and I just started using it about 3 week ago.

The media could not be loaded.  Used the product for 2 months. Worked well while it lasted. Light started flickering and the motor stopped working. Not sure what and why but the shaker just stopped working.

The media could not be loaded.  This is a handy mixer! It's the perfect size for a good serving when you're ready to use it. There's a cap that interlocks to the mouth piece that's meant to hold your powders, letting you serve it when you're ready to use it so things don't sit or go flat after resting for a while.The blend is nice, strong and effective for getting out clumps, making for a really mixed drink that's smooth. It comes with a small cleaner that's meant brush out anything left if you've let it set after using. This would be great for out on runs with a drink mix or after working out.

I really loved this blender for mixing powder based shakes (can't blend ice) but it has already stopped working. I keep it at my office to use - used it for 1-2 weeks then hadn't used it since. For reference I bought in mid-August it is not the 1st of October. Last week, out of the blue it turned on all by itself and I could not get it to turn off. I have not been able to get it to work since. I've tried recharging it twice now and still nothing. Really disappointed in this as I love the design, functionality and price point but the quality didn't hold up. :/

I really like this blender, no cables need it just needs to be charged and is ready to go, the battery is very good I have used it for a week and it is still charged, and you don't need a glass because you can drink directly from it, the material is good, it also comes with a Rechargeable Protein bottle that is very useful, you can also start the shaker while you are finishing your exercise and it will auto stop after a min, it's very easy to clean too, overall I like it because is easy to clean, easy to use, and very portable

These things are worth the $$. The Battery Life REALLY Long lasting. I haven't tested it until it's died yet, but I used it for shakes twice a day for 2 weeks on one charge and it was still going. I got worried and charged it. Obviously it isn't dishwasher safe b/c of the electronics, but it's super easy to clean by hand and it comes with a little cleaning wand. Very durable as well. I've had mine over 2 months and I have had NO issues. GREAT PRODUCT!!!

Me duro muy poco, trate de seguir las instrucciones de lavado y cuidado, sin embargo aun así no duro mas que unos meses.
