Product review (5 stars): Great meter
Excellent meter and quite accurate, I have found it accurate to +/- 0.2F. Uses a Sensiron SHT2x sensor, so it's quite accurate by design.
Wireless Serial reader and PC application are very helpful for remote reading.

Like any meter however it does need a little time to acclimate to the climate it's in, you can't take it from somewhere warm to cold or vise versa and expect an instant correct read.
