Review on Powerful Cordless Handheld Vacuum with 8000Pa Suction, 150W High Power, and USB Rechargeable Battery - Ideal for Home, Office, and Car Cleaning by Megan Johnson

Didn't realize it came with replacement blades making this a six star product. At first I thought I might as well throw the blades away because I'd probably lose them, but when I tried the can opener I found that the blades are actually very sharp. I had no problem opening a can of dog food. Ergonomic multi-function tool with a well thought-out design.
