A few unpleasant incidents....I was visiting from out of town and hadn't planned to dive, so wound up renting a broken BCD from them (literally the entire low pressure inflator had been completely ripped out of the BC, leaving a giant jagged hole in it). Sketchy but okay, maybe somehow they completely missed that. Except: they refused to exchange it for a functioning BCD when I pointed it out. I argued with them for about ten minutes before a much older and more experienced diver who was watching the whole exchange finally intervened and told them that it was bull**** and that the unit was clearly completely nonfunctional. It couldn't be inflated and couldn't hold air, because it had a massive gaping hole in it. They finally complied, grumbling, after that.
The same trip, a couple friends also ran OOA with them repeatedly while left completely unsupervised at the bottom of the pool doing a Discover Scuba from them; the husband called me, because he was upset...when I asked how much air was in the tank to begin with (how do you run OOA in a 10 foot pool?), he said he and his wife's tanks were both at 500 psi to begin with. I found that pretty unbelievable, so I asked him to send me a pic; he took a pic of the new tanks they were given after they ran out of air originally - again both tanks read about 500-600 psi. I'm guessing they were given them used tanks, it would be weird to go to the bother of filling them and then putting so little air in.
The whole thing (plus a few other minor incidents) just left a bad taste in my mouth....there's better folks to dive with and who I'd rather give me my money to, personally.
