Heck, I know people who have been disappointed by:
Ikelite
Subal
Seacam
Aquatica
Light and Motion
Nexus and
UK Germany
and many others.
The point is that EVERY COMPANY will have dis-satisfied customers. I don't think that anyone will be labeled as an "Aquatica basher" for posting legitimate concerns here. That's one of the things that Wetpixel's all about.
Things can and will go wrong - it's how a company deals with and fixes problems with their products that set them apart.
When I don't get a response to an email, I usually try calling. Not everyone these days is as "internet centric" as we are here at Wetpixel, so sometimes a phone call is better than an email, or is a necessary followup.
FWIW, I've gotten great service from most companies in this industry. I'd like to think that it's because I'm a nice guy, have a good attitude, and am willing to cut people some slack when they make honest mistakes. Heck, I make mistakes all of the time.
Cheers
