Things I liked: It was for the most part easy to install. Found a video online to show you how to do it. But there were some things that came up I wasn't sure how to work through without some trial and error. The accuracy and consistency is incredible! Made a really significant difference in my accuracy. Matter of fact, when I was testing it, I had to shoot a few times off my aim point to see if I was even hitting the target. Reason why was I kept putting the pellet into the same hole each time and started to wonder if I was actually missing the target completely! I'll see if I can post the pic of that target. FYI, I'm using the AT44 QE Long .25 and was shooting at 50 yards with the 33.95 grain JSB Heavy MKII pellets.

Things I would have changed: Provide instructions. Or at least a link to an instructional video from PA and/or Hatsan.

What others should know: Even though I got a huge boost in accuracy and consistency, I did however get LESS shots per fill. I previously got 3 mags (27 shots) of good shots unregulated. Now with the regulator installed, I'm getting only about 2 mags (18 shots). My guess is the regulator takes up some of the air volume in the cylinder, so in reality I'm probably not using more or the sale amount of air, but maybe a little less per fill. I was after accuracy and consistency at 100 yards rather than power, so I think I accomplished that. HMU @MikeKMyers on Twitter if you wanna bounce any questions off me.

Things I liked: Extremely easy install. Not having to drill a breathe hole is nice. Consistency. I noticed what I'm guessing is delrin was used for the regulator piston. That's fine if you're trying to keep costs down, but at $99 you can get an all metal precision regulator from somewhere else.

Things I would have changed: Plenum volume. The volume is tiny. The plenum space is set and non adjustable due to the way the regulator is made. Needs paperwork on install and adjustment.

What others should know: I bought two of these. One for a .22 short. One for a .22 long. The regulator on the short is perfect for plinking. Over 40 shots at 700fps with JSB 18.1's. I am disappointed with the regulator in my .22 Long. The plenum volume is too small to get a decent string at 30 fpe. I adjusted the output pressure up a couple of times to make up for the small plenum space, but it dropped the shot string to about 10 shots before coming off the regulator. That was even after I adjusted the hammer spring. If you want consistency you'll get it. If you're looking for adjustability, I don't think this is what you're looking for.
