Rated 4 out of 5 by Cormac Standard tubes
Takes air. Holds air. Doesn't puncture without undue stress. Fairly decent tube.

Rated 5 out of 5 by angryadam1 good pressure retention light
upgraded to these to get better pressure retention. all good work well and no problems so far loose far less pressure than average tubes. perhaps a tad expensive but worth it

Rated 5 out of 5 by ChickenT High quality, Zero duds
Unlike some other tubes, I've never found a dud one (this is painful to discover on the road, thank you very much conti supersonic). light weight, but not super light, does the job.
I also like these because the valve end is not un-screwable. I've had other tubes unscrew when inflating, never with these

What can I say? I bought these cause I needed spare tubes and these were the best price.
