overheat

Fair warning just mainly venting but its been a crappy couple days for me and my tank. Spent some time down in orlando and saw the awesome wwc and tsa tanks, loved seeign LIving reef orlandos farm and just really got that wild itch again to get my tank back tip top and fill it with morer...

Anyone ever use or hear or try this before... It has tons of positive reviews on the sellers so I thought maybe a try but wanted to check if anyone had tried it before? http://m.ebay.com/itm/282033379947?_mwBanner=1
