I fully tested all the features of this heater before using it in a turtle tank. The auto shut off works as it should. The temperature seems pretty close to plus or minus. Tested with 2 different thermometers. The only thing I would change is the suction cups and I wish it had suction cups on the front so I can mount it on the front for a better view. Overall I still give 5 stars. If anything changes I will update this review.
