After reading a lot of reviews of this device (also here on the forum) i've tried to buy the camera... and i'm happy with it. I've read about a lot of problems with the app, but on my samsung a52s works flawlessy.
I was worried about the lack of fusion mode of this type of camera, but the resolution and sensitivity is so high that i not feel the need of it. The macro lens allow crazy detailed photos of really small things.
The only thing that i not like too much is the compression used for the photos. The realtime image is much more detailed. I would love to have the ability to choose the compression level, or eventually get uncompressed images.
I know that they made some crappy marketing, but the product seem quite good, and compared to the other ir cameras that i have, is waaay better. And it's incredible as it's so small.
I was unsure if get the uni-t 260/271 or this one, that must be almost the same thing... i wanted a portable device with the macro lens, and i not liked the "gun" format. I've seen the tooltop t5 and t7 cameras (that must have the same sensor), but for have the macro, i've had to buy 2 cameras (t5 macro and t7 normal fixed focus), they not have the lens option.
