Review on Slime 50122 Flat Tire Puncture Emergency Kit: Sealant, Inflator Pump & 10 Min Fix for Cars & Highway Vehicles by Sean Patel

My wife tried to use it and couldn't turn the handle to pierce the sealant cartridge. When I got to the scene of the crime, it took me some strength to turn the dial to make it work. The screw on the stem connector is also poorly designed. I played this thing for what felt like an eternity until finally a strong connection was made. After that it was child's play. The gauge initially bounced all over the place until there was about 20 pounds of air in the tire. Unplugging the plugs deflated the tire about 5 pounds, so I'll inflate it even more next time. Overall not bad. He plugged the tire bolt leak long enough to get to the tire shop and they were able to plug it successfully. Attention, a replacement cartridge costs about 1/2 the cost of a new device. It has a new valve and inlet hose fitted as part of the assembly. Looks useless and overpriced.
