Love mine. Haven't had any issues with it thus far. Just as consistent over the chrono as my LG110, every bit as accurate too. All I have done was replace the screws for the hamster adjustment and butt hook adjustment with thumb screws so I can adjust on the fly.
Needs to be cleaned after every tin as best I can tell. After upwards of 5,000 pellets, it's still preforming flawlessly. Will be traveling by air with it next month, so we will see how things hold up being degassed and then refilled from empty. Hopefully there aren't any issues with the reg when I do this.
