I bought this because I saw a similar device on James May's Oh Cook! I didn't even know something like this existed but now I have it I think it's amazing. I did a lot of research on the 'slapchop' type devices and this one had the highest reviews and they were not wrong! I highly recommend this chopper - chops well, good build, robust, easy to clean. What more could you ask for.
Product is nice. The blades do not seem to turn with each chop as I expected it to. Takes a little longer to cut into smaller pieces than my Pampered Chef model. It is handy to chop up small amounts instead of taking out a large food processor.
The glue that attaches the plunger to the body of the device failed which caused the guard to become unsecured and get cut by the blade. Only used it twice.
It doesn’t chop onion unless it’s in smaller pieces and then gets stuck. I didn’t use the base to hold any food in. I had a different brand chopper years ago and was hoping this one would work as well if not better but didn’t unfortunately.
