The UNI-T UT306C infrared thermometer makes a good overall impression — it's convenient, quickly displays the temperature, and is suitable for household and garage tasks without any problems. It's important to note that the emissivity coefficient needs to be set for different materials, otherwise the readings may be inaccurate. A downside is that it comes without batteries, so you need to buy them separately. Overall, it's a functional and useful device.

Great device, answered my questions very well, and I am completely satisfied (the battery compartment is empty due to international shipping policies). I honestly loved the products of the UNI-T company. Good quality and reasonable prices My advice is to try to choose the product that has more options. Because there may be more than one model of the same item (of course, the price will vary slightly).

The order arrived well-packaged, without damage, without batteries. I inserted the batteries, tested a few things - it works. We will gradually get used to it.

I ordered the 306s by mistake instead of 306c, however, it works fine, no issues with it. It reads the temperature fast and it is accurate, from shorter distances (under 1m). At longer distances there seems to a be a minor difference of 2-3 degrees (lower).
