Rated 5 out of 5 by from Excellent and sturdy I bought 100 pcs a month ago for use in my company. The users have been very happy with the ease of use and the speed of the temp taking. We have bought more and recommended to others too.

Rated 4 out of 5 by from fast inspection of workers for covid-19 symptoms I bought this a few days ago and it works great for measuring the body temp of our workers as we test them for possible covid-19 infection. The only problem I had was getting it configured to show F and English commands vs the C and Chinese commands, which was the default configuration. The instructions on the Omega site were not quite accurate for reconfiguring but I found some other manuals and Youtube videos describing use of similar models and was able to figure out how to reconfigure it to F and English.

Rated 5 out of 5 by from Replacement My one of the two units broke down. I was pleased that they promptly sent a replacement. Company stands behind its customer service.

Rated 4 out of 5 by from 4 Stars Initially unit seemed to be giving low temps and without instructions it was hard to get used to but overall a great product. Took my temp today with the gun and an oral thermometer from work and they both gave the same temp!!

Rated 4 out of 5 by from Non-Contact IR Thermometer use review Overall it is a good product. Only draw back is temp range is wide enough causing a low temperature reading multiple occasion.
