I was planning to carry them as spares for my Southern Arizona Adventure Tour but I could not. They come in boxes that are 10 x 3.75 x 2.3 inches vs a normal tube box of 4.25 x 3 x 1.5 inches. I also did not have the time to mount them on my bike and do a thorough test before leaving. They seem sturdy (think garden hose)..On the other hand I did not have a flat during the tour with my standard tube and my Continental Gatorskin tires. So the jury is still out on my side.
Product Reviews Elsewhere Not Encouraging

I'm headed out on the ST route soon and needed thorn protection as I've read of the flats ahead. This tube brand appeared to be a good idea, however, I suggest people google reviews around the internet for this brand. I only read a few and they were not encouraging. Although they are thicker to resist punctures, their quality of manufacture apparently is the weak aspect to them and they fail.
