My first impression on seeing the product package was, “Wow, this thing is smaller than I thought.” After taking it out of the package it was, “Yep, pretty small, not going to do much onions with this.” I have now processed over 50 lbs. of onions over the last few days. So, I think I have enough experience to do a review worth something. My first recommendation is that if you are going to chop up a couple of onions for a meal, not to use this. While cleaning is not that hard, by the time you get it cleaned up, you could have simply chopped the onions with a good knife. The second thing is not to expect to chop a medium to large whole onion at one time. Won’t happen. I have a small garden and the reason I purchased this chopper was to process some onions to freeze. Before, I used a food processor and it pretty much just turned the onions to mush and they froze solid like a brick. I wanted something that would be more consistent and not create so much onion juice. I was not too sure this would work for me though. The finer blade seemed like it would cut the chunks a little too big. I definitely thought this was going to take a lot longer than expected because of how small it was. My first task was to figure out the best way to get the onions chopped and not just end up as long slices of onions. A little thought behind how an onion was laid out and how the device was going to push the onion through the blade I came up with my plan and stuck to it. You can see the results in the pictures I have attached to the review. Now for some details. Let’s take an onion. One of my typical onions is about 3-4 inches as in the pic with the ruler and onion. After the onion is peeled, you can see that it is a little large to go through the chopper whole. I cut the top and bottom off the onion, then cut down the middle. Laying the two ends flat I quartered each half. I found that placing a quarter chunk on the blades as shown would produce consistent chunks as can be seen by the pic with the chopped onion next to a ruler. The chunk size turns out to be just about the right size for cooking. Using this process, I peeled, cleaned, cut, and chopped about 20 lbs. of onions in about 3 hours this session. Cleanly cut the onions and extraordinarily little juice at all. Some onions are tougher than others. These may take a little more downward pressure than others. Do not try to use too big of chunks in the device. Keep them the size shown for best results. I quartered about 6-8 onions at a time and then used the device to chop them. The container that the onions fall in is small and does not take long to fill up. However, it was easy to just remove the top part and empty the onion into a bowl and continue. The bottom container is very clear and has 4 small rubber feet that does a good job of keeping it from sliding around on the table. I was not too sure how it would hold up. Except for the actual blades, it is all plastic. The blade and pusher part were easy to put in. The plastic seems to be very hard and showed no wear at all after all of these onions. Blade still seems to be sharp. It was easy to take apart to clean. The main section was easy to just rinse off. The blade section was also handled by just rinsing. The “pusher” section took a little more effort to clean. Even though they supplied a little brush to help get between the crevices, it was easier to simply soak it in water and then firmly tap the section against something solid to knock out all of the bit and pieces of onion that was lodge in between. Nothing to rust so I just dabbed off the excess water and packed away for the next time. Overall, it chopped consistent sized chunks. Onions were left in much better shape than a food processor. Even though it could not take too much onion at a time, it really did not take that long. I like the design and the functionality. Seemed durable and well made. I will use it again the next time. I now have peppers to do. I expect these will go just as well. I would love to see a larger stainless-steel device like this for those having to process a lot of onions. As a note, I am just about over a case of COVID-19. While I hope that it is temporary, it left me with literally no smelling capability at all – making doing all these onions a breeze :o) I would definitely recommend to others.
