stable By james on 2/25/2016james would recommend this product to a friendI was wary because of the other review on this but nothing has been as stable as this controller. Frankly I don't know how anyone would tell if their tank was 79 or 78 because every single thermometer I have found has a 2 degree accuracy range : (
Can't set to desired temp. By IdahoReefer on 8/18/2014IdahoReefer wouldn't recommend this product to a friendSet at 78f...does a great job of keeping my tank at 79.3f! My fault, should have realized that with 2 degree gap between settings, that it wasn't going to be as accurate as I was hoping for.
