This is not marketed a “professional” tool, like FL*R, at 10x the cost.

It’s low(ish)-res but the display works nicely. Best on short distances (1-3 meters, depending on object size). The nearer, the more precise readings - but the display can still show temp-diffs of 0.2c much further away.

As others have said, this works great for "basic tasks" (I mean that in a good way, I’ve checked things I never had the tools for before!).

So far I used it to find (prove) heat-leaks around some old windows, check brake-discs on my car for overheating, checked all the electric wiring in my apartment and a new car-charger setup.
The silicon-casing is a nice addition, anti-slip.

It’s so small I had to get used to avoid letting my fingertips being in the sensor-field. Had it in my pocket all day without even noticing. And the software is great once you get used to the buttons.

This was my first M5Stick product, and I'll definitely get some more :)

I have been fiddling arround with it and it's quite fun to se where the hottest part of my pc is so I can attack it more effectively

Perfect size for carrying in the pocket so it’s always available. The ability to connect to its internal web page wirelessly from anywhere is a really nice feature. Once you start taking it everywhere, you start finding all sorts of unexpected uses for it.

I mentioned it along with the M5StickCPlus/2 in this little video:

I purchased this T-Lite thermal camera for a bit of learning fun and use on checking temps on my vintage car and also bbq. It took me about a week to learn about the various requirements for using a thermal camera correctly (emissivness etc) and I have to say that I am very impressed. I've yet to connect it to my phone over wifi and all that biz (I'm not especially technical) but using as it came, with the built in screen, has completely served my original purposes.
