Guess it depends on the type of travel / camping you are doing as to have useful they are...on the move all the time I see them as a good space saver and they do work fine, but if camped in one spot for a week or two I don't see a huge advantage to them myself. Misses grabbed a few before we went away at Xmas where we stayed put for 2 weeks.... I took a normal towel away, because my arguement was it only saves a small amount of space for two days (travel to camp and home again), after that the towel is hanging up drying on the clothes line anyhow.
