I've rented jet skis a number of times and this was one of easiest experiences. The skis were in better condition than I've seen from some other places - only complaint is it would have been nice to have two identical models. I was pleased that the owner had already done a very thorough inspection of both units and had noted even more flaws/issues than I did.
Paperwork was easy - 3 sheets with a few signatures and initials. Pretty typical liability waivers, a brief overview on how not to get yourself killed, etc, etc. Just a heads up though, the credit card hold is $1000 - it wasn't unreasonable but might be a bit of a burden for some people.
Rental rates were basically the same as the competitors - slightly higher since we went on a weekend (as I recall, a some other places didn't charge extra for that). But I preferred to pay a little more and go with a place that didn't seem super sketchy - the Yelp reviews and BBB rating put my mind at ease, and the owner was always quick to answer calls.
Altogether had a blast at Lake Pleasant! Will rent here again next time I'm in the area and need some high speed entertainment.
