Review on 🚴 Sunlite Bike Tube, 700x18-23 (27x1) with 32mm PRESTA Valve by Brandon Miller

I bought 4 of these about a month ago. Long story short, ALL four had a tiny leak, less than a pinhole between the intake valve block and where it attaches to the base of the pipe. DO NOT buy these tubes. Of course the leak was very gradual and I couldn't find the cause until the last pipe died. The tube lasted a ride or two (no more than 10 miles per ride), and the next time I picked the bike up the tire was flat. (Note that I only go out once or twice a week.) I examined the tire with a fine-toothed comb after each tube died, but couldn't find anything in the tire to continue causing puncture. Finally I inflated the last tube and put it in soapy water to see where the leak was. When I found it I dug up other used pipes (I threw them in a drawer in my basement) and in fact they all had the same little leak in the same spot. Why didn't I check the first vial instead of waiting for the last one because such is life! Two lessons learned: 1. Make sure you find the cause of the apartment first time; and 2. never buy Sunlite tubes!
