Yeah, but keep in mind that thats the difference between a large company and a small one. An auto maker has money to invest (it has to also) in QC and testing. Some of these reef oriented companies dont have the facilities or resources to dedicate to extensive testing. The Vortec, for example, was merely a college grant research project started with something like $15,000 (cant remember exactly). Heck, I could have developed it because I have access to everything they do. So, the best way to 'test it out' is to offer 'pre-release' samples to a chosen few... as in a beta-testing group, to see what problems might happen. Software goes through public beta testing all the time as the more people test something, the more variables and chances for failure happen.
The one thing I dont agree with is that many of these reef companies make you pay for your beta testing, and then you keep the unit. They are trying to make money off the consumer in the process of him/her testing something for the company... doesnt sound fair. What SHOULD happen is the aquarist gets a beta sample free of charge, and then when the testing is over, the beta is sent back to the company for it to be dismantled and evaluated. If the aquarist wants one to keep, they can buy one at that point (hopefully at a discount for their service) from the actual release line. But paying full price for a beta, or being expected to keep a test sample? You gotta be outa your mind!
