product is terrible, first use the blades bent. I did check to make sure they were tight but still not what one would expect upon first use

Bought this slicer about a year ago and the blades that come with it are not very durable and don't maintain their sharpness. The blades have damaged the pusher and If you have to replace the blades and pusher, you might as well get another slicer. I will look for another one with the scalloped blades as they work a lot better and are more durable.

This thing is amazing! Onions? I think not, try onions, potatoes, lemons, oranges, pretty much anything you want put into slices this thing will do the job in a few seconds! Possibly the best prep tool I've ever bought!

Blades break very easily. After a period of use the minerals in the water you use when it is cleaned eventually corrodes the blades and when you put an onion in to slice it will eventually break. Replacing the blades is very difficult also.

Completely useless. Like others have said, the blades broke on the very first use. Everything was TIGHT. DO NOT BUY THIS SLICER.

This is awesome!!! We slice about 100 pounds of onions a week. So much easier and less time consuming than on a normal slicer. Well worth the money!!!

This machine is a real time saver. Slices onions with ease and at a very good width for burgers. Very good for a fast paced environment.

Outstanding piece of equipment! This machine allows me to free up labor to tend to other pressing things that need attention. It is so easy to use I had my son who is 11 try it and he used it with ease!
