A small drawback is the attachment of the air bag to the outer shell. The air cushions have been, so to speak just stuffed in the casing without further fastening except at the valves. As expected of safety valves, they can be prepared by internal pressures to not so easy to be working when in use. Unfortunately, the complete valve is me with this very quickly demolished and moved in the perception space of the envelope. This was a bit annoying, and would certainly be better solved.
Conclusion: A good water hammock with a small error, which is but bearable. Ideal for space and weight-saving transport.
