Not worth it
Color: Silver/Battery
I had this for four months and now it just shreds the cans. I tried replacing the batteries and that did not help. It makes tiny peices of metal that you get stuck in your fingers. Wouldn’t recommend

Very handy
Color: Silver/Battery
Easy to use once you figure it out. The lids are a little hard to get off the can once it is done, but I like the gadget.
