I have been using them for a couple of months now. Reviewed the movie that shows how to install them (just do a search online and you'll find it) as well as some additional clips that show how to fix punctures using a match instead of patches. I'm currently using them on the Betty and the Hunqapillar. Haven't had any flats yet and this isn't goat-head season so can't speak on that regard. On the Hunqapillar I'm using Marathon Duremes 40 which are puncture resistant anyway but in the Betty I'm running red Hetres. Not a lot of mileage, unfortunately, but no issues whatsoever. Perhaps they tend to lose air a bit faster than the Schwalbe tubes I was using, but not a big deal. Had two Schwalbe tubes slowly deflate overnight with no apparent punctures, perhaps just a bad batch or some micro-puncture I couldn't detect with the usual methods.
