If you're thinking about getting one I'd recommend this version says 850 lbs or 875 limit. Pumping up takes about 5 minutes. Just get it to a good inflation with the electric pump and finish with hand pump for the gauge. We inflated to 5lbs. Brought It to the springs and a lake. No issues and my friends kids had a blast on the lake. Only down side it doesn't come with the glue for the patches but you can pick that up at home depot.
