I think the problem here is that your first system was a 1705 and not an M1710 or M1730. I was told that if they had to replace my system, it would be a system equal or better than my original system, which was an M1710 that they could never get fixed because it overheated all the time. If they refund me the $2500 I paid for the M1710 plus the $300 I paid to extend my warranty, Then I will be pleased.
