We received them in good condition and on time! We bought several to check temperatures in all of our refrigerators and freezers. They work well. They will help us to know if the temperatures deviate from normal.

Works as intended!Handy tool to have on hand!Temperature accurate 👌

Great price, easy to read, a must have for A/C work. I keep one in the vents of each vehicle without issue.

Small dial, hard to read but does the job.

Works well and a decent price

The Plastic Material with Clip just slips into the vent and clips in. Very High Quality and the Temperature reads good on it. Also it is Waterproof.

A quick, inexpensive tool to test temperatures in HVAC systems. It's a handy pocket tool to take quick temperature readings in HVAC outlets, automotive A/C, and kitchen refrigeration equipment.

Some of the numbers are a bit hard to read but it's highly effective. I use it for meat and for the ac and it's great.
