We had the version that rolled up on a reel and was very thin.
The problem was you need good
water pressure to get them to "inflate".
We were at the
marine in
Bonaire years ago trying to fill our
water tanks with it and no water came out. The collapsed hose pinched off the very low water pressure flow.
We then switched to our non-collapsing Swan garden hose and got water flow to fill the
tanks.
TIPS:
If you are a long way out on the
dock, don't expect very good water flow.
If it is summer time and there is little water flow, walk the
dock to make sure that
kids don't have all the taps turned on to squirt water at each other. You will have no water flow if that is happening!
