I looked seriously at that fridge, but ended up getting an Evakool fm70 instead, major reason was the height limit if I wanted to keep it in the trailer but also because Evakools good reputation with a 5yr nationwide warranty, plenty of good feedback available online and picked it up for less than the techniice fridge, In the reviews about the techniice that I did find, people were happy with them but there weren't many reviews and none really dealing with it's longevity. If you look at Evakools specials page you can often find some good deals.
http://www.evakool.com/factory-seconds/hotspecialsI don't know if Evakool actually do this but I have known companies to sell, ex-demo/damaged box/factory second etc items that are new and perfect but sell them as this to be able to sell at a reduced price without upsetting the normal retailers of their stock. Might be the case with some of the stock but then again might not but look like they all carry their full warranty (although different lines do vary in length)
