Review on Slime Smart 1 75 2 125 Healing Mountain by Marcus Britton

First of all I'm a former bike mechanic, I know what I'm doing. 2 of those "heavy slime tubes" to reduce the number of times I have to disassemble a rear tire on two bikes. The first one I installed lasted a month or two with careful driving on concrete paths about 2 times a week. There was no air this morning. It turns out that the valve is cracked at the valve/pipe junction. Garbage. The hole in the rim is even and clean. The second I unrolled to replace the rear tube on the 2nd similar bike, I disassembled the bike, removed the old tube (it flew off - another garbage stem), cleaned everything, checked for burrs, etc. everything is fine . Went to insert a new slime tube. Too small. The second tube they sent has EXACTLY the same markings as the first, in the EXACT same box, all marked 26 inches. It's actually a 24" tube. Not useful as I don't have bikes with 24" wheels. Rubbish. I'll take my other bike to Target and buy two pre-made tubes. At least these cameras know they're cheaper These expensive slime tubes cost good money. :(
