I've been to these guys a couple of times and to be honest they are terrible. The staff are young, rude and unhelpful. The rates are very expensive. Since the accident at Chatfield, they have been pulling customers off of their jet skis prematurely. So if you want to spend $75 (on top of that they charge for oil and gas!) for 20 minutes go ahead. Make sure you follow the rules to the T, otherwise they will pull you in.
They are the only shop at Chatfield, so they are convenient, but they will rip you off, your choice.
Someone needs to offer an alternative to these people.
Cons: Expensive, Will rip you off, Rude and unhelpful
