Product review (5 stars): As described.
Works as described.  I use this with a chest freezer.  The cord is very thin so the top of the freezer closes securely even with the cord running under it.  The temperature displays in celsius which I suppose is a little annoying, but that was clearly stated in the item description so I knew what I was getting.  It would be great if the display had a magnet so it would stay attached to the freezer rather than hanging down or falling every time I open the lid, but again for the price I can't complain.
