I always talk about the 30 meters. It is blue in color (not that it matters) and it didn't puncture like I was afraid it would. It seems to be exactly as the manufacturer describes. I have no complaints, it expands when filled with water, and to shrink it, we pour out the water inside with the faucet closed. Its downside, which cost it a star, is that the adapter included in the package is smaller than my faucet, and I was forced to buy another one. You need to be careful to pull up the blue cover (@) after you screw it on so that water doesn't leak from the connection.
