Bests & Worsts Reviews from Amazon

Going on my 3rd unit in a 10 days! First unit leaked water from the back panel right away. Called Amazon and got another one sent out (UPS call tag sent for defect) Second unit came in 2 days and also leaked from the back panel, but the drain outlet on the back was pushed in and cracked! Called Amazon and they sent out a third unit (UPS call tag sent again). All was well and working for 2 days, AND again leaking from the BACK! Many state this is a wonderful product and I have had earlier models, with no problem. There must have been a bad run at one time and something is not right inside with the run-off. There may be insulation missing on the piping or just not properly applied. Will call a service center and find out if there is a known issue with these units. If not, I will call Amazon for perhaps the FAD704 DUD (earlier model) It's not Amazons fault and they have been great in handling this situation (shipping and returns) Will advise.
