What do you think about DEI?

 I am using a rattler 300 by DEi.  This is my 1st DEI product.  I always used Alpine, but this time it was a gift.  I have had problems with them, however found out that it was not the company, but rather the dealer KRAZY KRAZY.  The installers are kids, and do not know what they are doing.  I am not a installer, but I could have did a better job.  As far a customer support from DEI, I had written the head office in Montreal Canada, and was sent a new transmitter in days, along with a nice letter from the head of customer service.  The transmitter was defective (water damages) from the dealer I was told.

DEI seems a bit eliteist when it comes to documentation, info and warranty (none of which are available to do it yourself folk) On the other hand if they put all the info out there, people would get overconfident all wire themselves into trouble.
