Just received and so far am very impressed. I want this to trace my central heating pipes in my house, and it is incredibly useful for that purpose. Really easy to see where the hot pipes are behind walls, ceilings, under floors etc.
Saves a lot of pictures – don’t think there is any way to remove or transfer the memory which would be helpful, but being able to take loads of pictures of the readings is great.
Accuracy / precision seems very good. Quite a wide field of view, which is good – easy to see hotspots, then just move closer for precise details.
So far, reallly happy with this. I wanted one years ago but wasn’t going to spend hundreds of pounds, but at this price was happy to get one, and very glad i did.

It’s a good product, it has several colors to display the surface temperature. The only downside is that there is no regular photo mode (to make it clear that the photo in front of you is taken without a thermal imager), but otherwise I’m quite satisfied.

Great unit for people on a budget.
Not incredibly detailed but for its price and output, battery life and usability it’s excellent!
Has internal memory for images to be saved and uploaded to pc.

Excellent product, I have used FLIR brand thermal imaging cameras many times and this camera has nothing to envy them except for the resolution, which is obviously lower, and the fact that it has an external SD memory card, but 8 GB of internal memory is more than enough and it provides mixed images. However, for insulation checks on windows or walls and for checking overheating in electrical networks or circuits, it is perfect.

Very quick delivery to the uk. Great thermal camera for £70, 96 x 96 thermal resolution is fine for viewing heating system and i used this to balance my central heating system. Temperature is accurate and the camera is simple to operate, pretty chunky and robust with good battery life.

Good, you can check if the boiler is running well and see if there are any drafts or other issues.
Considering that the human body temperature is around 35 degrees, the correction value of 0.95 for the material difference seems to be accurate, so the temperature seems to be precise as well.

Very good equipment, dynamic temperature measurement, reflection of shapes and temperature spectrum. Excellent quality at a low price. The description stated that the menu has a Polish language option, which is not true. It does not have a Polish language option, but it is still easy to use. An additional advantage is the ability to save measurement photos to memory.

The camera started up after charging. Not sure how accurate the temperature readings are but it certainly does show where hot or cold spots are for looking for insulation. The camera refresh is slow so you need to move the camera very slowly but not an issue for me.
