Review on 🔧 Enhanced Tire Valve Caps (12 Pack) - Heavy-Duty Stem Covers with O Rubber Seal for Dust-Proof Protection - Hexagon Design, All-Weather & Leak-Proof Air Protection - Lightweight Universal Aluminum Alloy (Gun Gray) by Steven Guevara

Bought about a year ago. Put them on all four hoops. New tires at the time and they don't seal the bead like the old ones so I check the air and top up if needed about every month or so. Hats were always taken off and put on again without any problems. Until last weekend. Went to check tire pressure and not one but ALL four were stuck and wouldn't come loose. Took two off with heat, a vise and a percussion tool but two are still stuck. I put some oil on them to penetrate them and try again. Now I look at the listing and see a warning that they can stick. I'm 99% sure they weren't there when I bought them. If that were the case, I would never have bought them. IMO stay away from them.
