Review on Infrared Thermal Resolution Temperature 20 300°C by Dan Weeman

I know you need a cheaper thermal imager to get the job done like me. This one is very, very, very low resolution, and the picture is just a bunch of clutter. It can detect a person's existence, but if you want to refine some details, e.g. For example, where the draft is coming from behind a window frame, it can only show a large area of blue in the image that roughly tells you where it's cold. Useless. I had a Flir TG 156 that sells for $379 and it worked great. Something like this is really worth over 300€. If you want to save money, you can rent for $50 for 4 hours. Also expensive and if you want to use it again you have to rent it again. Whatever you choose is just the price of a thermal imaging camera and this HT-02D is a waste of money. I'm really baffled as to why something like this could even be on the market. I can make it worse and sell it for $50.
