I had my unit about 8 months before one unit failed. It leaked water from the unit out under my bed. They promptly fixed it (but I paid outgoing shipping). They told me to put a pan under it as well. months later the other units remote will only work within several feet of the unit. Ont op of that it failed completely shortly after that started happening. Instead of cooling it, it heated the bed. i.e. I placed it at 66 overnight and the next morning it was 81. Again they promise to repair it (i pay outgoing shipping again). lastly and most importantly their own site says you are most comfortable at 65-68 but there unit will almost never get down to 68. If you leave it on all night in a room that's 75 or so ..you might get it down to 68 or 69. I have learned to live with that but its certainly not what they promise you. The rep. said nothing can be done about it but said it wasn't right it wouldn't go lower than that. Overall, its great for hot sleepers...when it works & as long as you dont need it to cold or to get to cool very fast.
