They are good, the only negatives in my mind are that the temperature is in C vs F and you can't change it (that I am aware) and most importantly was that it took weeks to come in.  I love the size and perfect for what I needed them for.  I am purchasing 10 more but due to the lack of timeliness will be going with another company.  Which is too bac since I liked these much more than the other company who also charge 2x.
