Review on 🔧 Parts Express 3in1 Container Bottle Jar Lid Can Opener: Easy Twist Kitchen Tool with Silicon Jar Opener and Screw Cap Jar Bottle Wrench - Random Colors (Red, Green, Blue) by Jerome Turner

So. it wasn't at all what I thought I was getting. I have a stubborn cup lid that won't come off and I was hoping this would help. It was of no use. First off, the "large" size isn't very large at all, so it doesn't even fit around a cup. The small teeth inside actually do the opposite of what they were designed to do - they reduce the friction required to open. I also tried using on a regular glass. It didn't work either. Also, it's too flexible so you don't really have anything to hold on to (the 'handle' disappears to fit around the glass). All in all, don't waste your money.
