Things I liked: Solves the problem with knowing how much air remains in the tank.
Things I would have changed: The clearance between the gauge and the frame made installation difficult. I was finally able to install the tank but I rubbed the finish off the frame in the process. I have asked Pryamid Air what I can do to protect the frame where the gauge rubbed off the finish. Although I have not yet heard back from them, I am still very pleased with the ability to know just how much air remains in the tank.
What others should know: The problem I had may be a transient quality control problem but I would ask about this before buying.
Things I liked: I really like the weight and design of the pellets. The extra weight has a great impact on game.
Things I would have changed: The skirt dimensions vary some from pellet to pellet. The result is a little variance in accuracy. Otherwise a great product.
