Title: Slime has gone downhill
Review: I used to swear by pre-Slimed tubes - I used them in my bikes for at least 5 years - but I've stopped using them because they've become unreliable.The idea behind pre-Slimed tubes is great. The tubes come with just the right amount of an anti-flat goo already loaded in them so that the tire can fix itself if you get a small/medium puncture flat. This self-sealing action lessens the risk of a sudden flat that throws you off your bike since the tire deflates slowly. You'll probably be able to make it home before being forced to change the flat.I used these tubes for years and everything was great. Unfortunately, this year I've gotten a series of tubes that all failed at the valve stem within a few days of installation. The tubes were installed properly, one even by a professional. I wonder if the company that makes these changed their manufacturing process (cheaper! faster!). Anyway, I can't use something that I can't rely on.Therefore, one star.
Is the review positive or negative?
