Product review (4 stars): Locks up on regular basis
Worked great for the first 2 weeks. Then it would lock up on an inaccurate termp. The only way that I'm able to use it is by constantly turning it on and off. I replaced the battery and it still has issues. I don't consider it an accurate measuring device.

Update: Was contacted by the company and they resolved the problem with the problem thermostat. Greatly appreciated.
