Cant beat the price! Came with 2 extra batteries also!! Works like a charm!

Needed a cheap thermometer to peek at my tub without taking the lid off, i ran the probe right through the air exchange hole and used double-sided mounting tape to stick it about 1" above my substrate and I found out that I had it too warm! Very accurate and easy to read!

My new probe thermometer is great. So much better than my old, non-probe

one which I could not leave in a grow tub for very long before it would fog up.

 

This little thermometer is great! Works like a charm!
