This is really unfortunate to hear. I have actually been somewhat satisfied with my new Dolphin. I have a freeform pool and it has seemed to work well for me these past several weeks. But, as you say, how can I keep something knowing that when I need product support the manufacturer won't be there. If Maytronics can't address this because of the current events in Israel they could at least send you an email indicating they will follow up as soon as reasonably possible.

If you were in Texas I would recommend sending a DTPA (Deceptive Trade Practices Act) demand letter. The law here allows you to collect treble damages for warranty representations which are not fulfilled. I would suggest contacting your State Attorney General's office (web site) to research your rights of remedy.

Best of luck to you. My unit will be returned this Saturday. I'm in the market now for another unit. I'm really thankful to see all the great folks on the forum stepping up with their reviews of alternatives.
