What do you want to do with it? It is worth the money if it meets your needs, so what are the needs? Are you looking to hunt inside 100 yards or more like out to 200? If the latter, you will be disappointed. Can you use it out that far? Sure, but the image will be awfully blurry.
This is a pretty good video. It looks to be very good conditions with a lot of the target animals nearly fully exposed (versus being partially/mostly hidden in vegetation). It was shot during much cooler weather (animals stand out better) and I suspect in lower humidity conditions.
What I particularly like about the video is that they mention the distances being shot, something most folks don't do.
With all that said, the PTS233 looks pretty good, but again, these appear to be really good conditions. Most folks that I know that purchased PTS233s either hunt infrequently, have relegated it to a spotter and/or guest scope and bought a better scope, or sold it off and bought a better scope with the exception of one guy that I know that uses his quite a bit for what I call barnyard hunting. He protects livestock around his barnyard with his and loves it. He doesn't usually shoot more than 75 yards or so and could not be happier for the job that it is doing for him.
The problem that you are going to have with this sort of scope is making proper identifications of similar looking animals at distance. That is going to be because of the small lens size and lower resolution. Telling the difference between young calves, deer, and hogs can be difficult with good thermal with higher resolution and better imagery. Telling the difference between a coyote and the landowner's dog can be a problem if you aren't careful. Take your time and learn to identify targets properly, regardless of the quality of thermal you use.
