This is a copy of an email I got from Blue Diamond... I asked to compare the Blue Diamond Remote and the Dolphin Diagnostic Remote from Costco for $999.99...

>Dear Tom:

Comparing the Blue Diamond Da Vinci Remote with the Dolphin Diagnostic is like comparing a Rolls Royce with a Buick. Dolphin does not make a high end product like Aqua Products and Water Tech do. Aqua Products version is experimental and far from being market or time tested. In fact, many have come back as being defective. The Dolphin Diagnostic is on the same level as the Aquabot Turbo Remote Control, a mid-level cleaner, while the Da Vinci is in a much higher class. O assume you have seen our comparison charts.<
