I own this model. It's great. Thought the body would be metal like the P2, but it's got a thinner feel. Still, I'd rather they put the cost into the sensor and image quality.

This thing is better than it has any right to be. The image clarity is better than I expected for the price.

Keeping it on a working man's level, one of the reasons I follow and watch all of your reviews on tools.
Hard to believe a $99 thermal can look this good. TM must have some real engineers who actually design their own stuff instead of just slapping parts together. That's probably why they can sell it for that price and still make something that works damn well.

compared with Flir One Pro, seek compact, and TopdonTc001, finally choosed p1, VERY satisfied now

I am a Facilities Manager in large Level 1 Trama Center/Teaching Hospital in Montreal. Water leaks in our facility were weekly events. I used a thermo camera to find sources of leaks and wet walls. I can honestly say the P1 gives the best value out of all the ones I've tried. Before the P1 I mostly used a FLIR phone cam. It is moody often, takes forever to connect and the resolution doesn't look as smooth. And yes I've adjusted my camera alignment and have the pro version. Flir does a lousy job updating their app too and support sux.

IR-cams like these have a much better price-to-performance ratio than some FLIR handhelds. Not considering anything else but the resolution (so you may want to take closer comparison yourself), the cheapest gun-style-with-sceen 160×120 FLIR is 500 bucks and the cheapest 160×120 in the same dongle format is still 300 bucks. 160×120 is not even that bad. A 320x240 P1 costs 143 bucks on Ali, but there are also 256x192 dongle ones for 200 bucks (with a temp range of -20°C~+50°C, but 50 Hz instead, I guess, but also there are things like thermal sensitivity (NETD)), so obviously, resolution is not everything, so again, you may want to-do a lil deep dive into this topic, videos on the big video site explain the characteristics and what metters.
