This chopper and blade are made of nice quality and are sturdy. Unfortunately when it came to chopping onions it did not perform as well as I expected. I cut the onions in half and the chopper still struggled to chop them all the way through, if I used more pressure it would squish the juice out of the last couple layers. I use a lot of chopped onions for my restaurant and was hoping that this would save us a time but now is just sitting in storage. It might work better for softer items.
