If you look around at various airbeds a common problem appears with them all...deflation.
This one is just the same inflated twice so far, once as a test which went well, plug it in switch on, walk away have a cuppa, return and switch off perfect for camping. So the problem is its fine if you put no weight on it, stays inflated for 12 hours no problem.
On the campsite is another story, if you picture a live fish on the river bank, well that was us trying to get off the damn thing in the morning.
Cant find the leak but the best so far was 4 hours before having to reinflate.
Buy one for hilarious mornings but not a good nights sleep.
