Exceptional Performance, Easy to Use and Clean, Quality Feel, Will Buy Again
Exceptional in ease of use, easy cleaning, and performance. Too early to tell about long term quality but it does feel like it will last. I do a log of freeze drying and it has handled everything I have used it to slice fresh and frozen items with ease. The hopper design makes it easy to work with handfuls of chunks of food. For example, I buy large packages of ginger, peel and slice 4mm thick slices for freeze drying. With this, after peeling, I can toss in a handfuls of ginger in the hopper and slice them perfectly in a few seconds. It disassembles easily for cleaning and storage. Would absolutely buy again, and probably will as a gift.

Most Excellent Chopper!!
This is by far the first chopper that I found that can chop a sweet potato! It also has different settings of thickness where other brands you do not get the option to create a thicker cut! The chopper is very easy to put together and it’s very quick and easy to use and best of all it’s extremely affordable! This is one product I will not ever be returning, but I definitely will be telling a lot of people about it! I’m very excited to be able to chop things in a quick safe manner without cutting my hands up! On a scale of one to 10 a total 10!!!!!

Good
Cuts well. Some pieces may not look exactly like others but this thing does cut and saves time on prepping food. Easy to use. Very glad it came with a cleaning tool. Easy to clean. Easy set up. Stays on counter well while being used.

Don't despair at seeing the broken and misspelled English on the box and in the manual
Despite the manufacturer not being able to accurately translate and spellcheck the manual (the first thing you see in the manual is a section called "safty"), this is a fantastic item, fully worth the money. The engineering is clever, sturdy, and (with one exception) very well thought out. It does exactly what is says it does, although the learning curve on how to set the dials for certain cuts is slightly hampered by the bad English in the manual. Experimentation... risking a few cheap potatoes being random cuts... fixes that easily enough. The actual use, the actual cutting, is super easy and fairly consistent. There's always a few awkward cuts if the vegetable is oddly shaped and moves around a bit before you can fully stabilize it with the pusher thing (with longer vegetables you're going to be starting with hand pressure instead and switch to the pusher latet), but it's overall a snap to use. The input seems far larger than the Dash brand Mandoline that does the same thing. Okay, now onto the obvious weakness: it's clear that blade is eventually going to dull. It's non-replacable. When you dissamble it to clean it (the ONLY time there's even a minor chance of cutting yourself) you can see the blade is permanently bolted on. There's no clever engineering to make it removable and replaceable. In theory if they bothered to sell it, the entire cartridge assembly inside which includes the blade is probably replaceable... but given the shipping cost from Chins even if you CAN contact them, be understood, and properly make payment, I bet it would cost almost as much as buying a whole new mandoline. Hopefully that blade stays reasonably sharp for a few years. Note the disassembly and cleaning is also ridiculously easy. This is about a 4.5 of 5 for me due to the obvious planned obscelesance, but since we can't give half stars I'm settling on 4. If you have money to burn and don't mind potentially having to replace it with an identical unit when the blade dulls, then consider it 5 stars. It really DOES work that well. Oh... the one other minor ding besides deciphering the manual and the inevitable dulling is that it can't really chop (versus slice, julienne, etc). Their instruction for that is basically "put it through twice". Which is fine. That said, a $10 hand chopper is probably easier for that.

It works well!
I am really impressed with this mandoline slicer! Years ago I had a mandoline slicer and finally gave it away because on the old one, I'd cut my fingers on the super-sharp blade numerous times. The blade(s) on this one are equally as sharp but it is well designed to prevent sliced fingers. If you really tried hard, you could cut yourself, but if you follow the precautions in the instruction booklet, you will keep your skin intact. Anyway, when I deboxed it, I sat down to read the booklet. It seemed kind of complicated at first, but actually isn't. The next day, when I used it, I remembered what I had read and along with using common sense about how things work, I successfully ran its slicing function without having to consult the book again (onions for Indian food). Features I like the best: 1. The food chute is generously sized (I cut a medium-sized onion in quarters and the chute is large enough that I got 2 of the quarters in the chute at once). 2. The plunger that works the slicing runs smoothly and has a substantial feel. 3. The rubber/silicone strip on the base of the unit eliminates slipping. 4. The food catcher caught virtually all of the onions and hot peppers that I sliced. 5. You don't have to change blades to use the julienne or chopping functions; via flipping a little switch, little triangular blades pop up to change the shape of the slices ( I haven't yet used the julienne or chopping functions yet, but if I have trouble with those I will update my review) - this is a terrific safety feature. This is a very good product!

Finally… a mandoline that won’t take my fingers off
I just got the ONCE FOR ALL Upgrade Safe Mandoline Slicer and I am honestly impressed. I bought this specifically to slice sweet potatoes (which are usually a pain), and this thing makes it SO easy. The biggest selling point for me was safety—and it definitely delivers. The blade is enclosed, so you don’t feel like you’re risking your fingers every time you use it. It feels really sturdy and well-made, not flimsy like some kitchen gadgets. Assembly was quick and simple, and I had it ready to go in minutes. Once I started using it, the slices were consistent and smooth with hardly any effort. If you’ve ever struggled with cutting tougher vegetables like sweet potatoes, this is a game changer. Safe, easy, and actually works like it’s supposed to. Highly recommend!

A very nice slicer
Our old slicer was getting dull so we needed a new one. After searching a bit I settled on this one. It works really well. I like that I can change the settings for different type cuts. Its very simple to use and more importantly, safe to use. Our old one you had to be careful you didnt get your finger at the end of the potatoe or whatever you were slicing. This one has a push tool so your fingers never get close. Its safe to put in the dishwasher but with all knives and such it's better to hand wash to preserve the cutting edge. The blade is extremely sharp right out of the box. A very nice slicer for the price

Mandolin
It’s difficult to use and the suction cups don’t stay so it’s unstable. I personally don’t like it but my husband does the mandolin thing for me. It works great and the blades are sharp, it’s not described as seller says
