FLIR One Pro LT Thermal Imaging Camera Attachment (Micro USB) w/ USB-C Adapter Expired

This price is almost the norm so there's no need to rush into this.

I have this micro usb version with my Samsung S9+ and it works fine.
The bad reviews in the app store might be compatibility issue. The same App for multiple versions of the camera make it hard to tell.

The USB C version says: FLIR one Android sub c models are not currently compatible with snapdragon 835/845 based Android sub c handsets

So, I bought this micro usb version to use with my USB C phone. It does work!
I really would have preferred the USB C model to be more future proof though.
I have used this to find leaks in my AC ducts and it worked! It also shows me where I should probably wrap my ducts more because of the cold leaking out.
I have also used it to find my pets in the dark
It also shows me where my carpet might be wet because of my pets -_-

There's a lot of uses and I have only scratched the surface.

The resolution isn't great so don't expect something out of the movies. Imagine colorful blurs. You can take a thermal picture with the app and within the app, Then, you can hide the thermal colors to show the picture under it. Using this method, you can determine where the colors were coming from.
It auto adjusts the range, but you can also set a range. For example, to find the ac leaks, I set it low so that everything in the attic was bright yellow (warm to hot) and the blue shadows (colder) were the leaks. If it were auto, the ducts would be moderately bright and everything else would be darker, the blue shadows would be harder to find.
I think it would make finding a literal needle in a haystack doable! But then, a magnet might work better. You need the right tool for the job!

This is useless without the app, and the app has shitty reviews, therefore this device is functionally shitty. It doesn't really matter if it's physically very good if you can't use it.

This is a true statement, worse then this there is an issue with the battery discharging on these and damaging a cell. Well documented online, denied by flir. I recommend doing a search on the battery issue of this prior to purchase.
