    Have only had a few cooler nights, but the temperature has remained well within usable range. Only thing I don’t like is the form factor of the production product versus the prototypes I’ve seen pictures of. The large round disk shape makes it harder to find a place for. The flatter “brick” shape version I saw on the prototype photos would fit my cramped workspace better. In the end I had to position it top/rear of my machine, whereas the brick I could have fit under my bench on top of my chiller. Overall pleased with my purchase and this will hopefully save me from replacing a shattered tube like I did last year due to cold. I knew of the new disk shape prior to ordering, so that’s on me. Good product!
