Bests & Worsts Reviews from Amazon

I was given this as a Christmas gift. Checked to see that it worked...and it did...put it away for spring planting. Checked it again. Set would not go out of Centigrade. figured I would work with that...but today when I set the whole thing up ready to start, The controller doesn't not work at all. needless to say I am extremely unhappy and so are my 42 tomatoes. My husband is also unhappy as he is the one that got me the much wanted seed mat for Christmas. not at all a happy customer.
