KKmoon Digital Thermal Imager, 2.4 Inch LCD 320x240 Handheld Thermograph Camera Infrared Temperature Sensor Built-in Lithium Battery, -40℃~300℃

Clever little product for the price. The buttons are a bit small and finicky but once you get your head around the settings, you only need to press one repeatedly.The colour coding is easy to understand and I used this imager to diagnose the temperature differences in my floors, windows and walls.It's amazing how much this differs, and is valuable information in helping decide how best to heat, insulate or cool a room.Such a valuable tool.

The first impression is small light thermal camera that performs better than I would have expected. I was concerned about the lack of marking on the unit or printed instructions (hence the loss of a star). There are, however, some basic instructions on the Amazon website for the product. It certainly does what I need of it but a full explanation would be useful.

Very poor quality picture is undefinable design of unit worthy of a Christmas cracker

This item came without instructions and not working.

Product arrived with a cracked case. See image.Also, has no instructions!
