Installed easily due to thickness, so far 520 miles with no flats. It is a heavy tube though, I weighed it at 375 grams. I'm using them for training now and will switch to a standard tube when I ride my century this year.
i bought this tube because i hate flats and people in my town like to throw glass bottles in the road. i haven't gotten one yet. it is a little heavier which is a draw back if you are weight conscience. If you are a commuter on an older bike or just need a little more protection from a tube, you should buy this one.
