I do like the primos, it has performed flawlessly so far and seems to be pretty easy on batteries. The IR flash doesn't quite fill the entire shot, a little dark at the edges but for $99 i've been very happy with them. The temp and moonphase are pretty cool for a camera in this price range. I'd like to try one of the 45s and see if does any better filling the frame with the IR flash. Trigger speed seems to be fine, not many but shots or blank frames so overall i've been pleased and would recommend it if you're looking for a good cheap camera.
