Product review (4 stars): Good deal, good device
This thermometer is still going for me after about 4 months, pretty good for the price, and I just replaced the batteries for the first time as well. I find it to be accurate within a few degrees compared to other thermostats but I don't have the proper tools to measure completely objectively so take that with a grain of salt. The wire on it is quite thin but has not been damaged by light wear, and the screen flickers pretty badly as the batteries get low.

Edit: The seller has reached out to me in regards to my screen flickering problems and offered a new unit. I've updated my review by another star to reflect the great customer service and attention provided. Thanks Qooltek!
