Review on Digital Freezer Thermometer Temperature Feature by Kristina Soucy

Trying to use this on a freezer that tends not to close fully, especially when in a hurry. Tried to set the alarm several times. But it looks like it should work and will let you know if it's hitting the highest low rather than just setting the temp to let me know when the freezer is mostly open. PLUS if you mount it outside; You will need to route the sensor cable through the grommets lining the door surrounding each fridge/freezer. And the; lead to the formation of condensation and ice at the cable entry points. Do not mount the sensor on an outside wall, even with American frost-free freezers! He registered 45F and the alarm went off!
