I recently purchased the ATN 4K pro. Have not shot anything with it yet but have taken it out and played with it a lot. Could easily identify a raccoon at 150 yards. And with a streamlight IR illuminator deer at 275 (known distance). Feel for my budget in a toy that is going to shoot hogs 2-3 times a year it works way better than I expected.
It has worked without any issues also.

Buddy from work uses his 3-4 night a week shooting hogs at his farm and has had no issues.

There is way better on the market, but it also cost way more. If your a serious night hunter obviously spend the $ for thermal.
