Bought one from Schwinn (Quality?) one day later flat..
Why do they make them so damn thin, like condom thin?
So when they get a hole, they really get a hole.
I had a slime tube for a very short time and a 2cm gash one day, that ain't sealing!
Better off getting a thick tube, I have thick tubes on my bike now and no flats all last summer, and a lot of off road use too.
