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.

Failed at 3 months.
Color: Silver/Battery
I ordered this on Oct 6th. When I first got it, it worked great. I didn't need to use it all that often but here it is, 3 months later, and it is broken. It fails to cut open any cans. Tried on multiple cans over multiple times but it just spins cutting nothing. Total waste of money. Avoid this product if you care about durability or longevity of your purchases.
