Digital Thermometer 0.1 degree resolution, lasts forever on single battery
For the money, its hard to beat.

Size and shape as advertised. Performance lacking
8 of 9 found this helpful This TEC does meet mechanical specs. But its cold pumping ability less than half of what you would expect for a similar sized American made device. For instance with a delta T of under 5 degrees C, its COP was only 1.5. Normally you would expect to get up to 10 watts of cooling for 5 watts of power in (COP=2) when the delta T was up to 10 degrees C.

Lightweight and mostly functional
Using it for a simple fan speed control in the lab. Works as required, but the plug in the outlet has to be wiggled around to make good contact every time I plug it in.
