The AA is a good buy in co2.
In pcp its way too expensive.
Also, its air reservoir is way too small.
Grip is too thin.
Its VERY light upfront, as its all alu. And the air RIFLE barrelweight that comes with it, doesnt make it balance any better (now too heavy).
Also quite cranked up speed wise, not that much shots (I had a co2).
VERY tiny bolt to cock.

Imo, the Tau 7 is a far better buy; adj grip, thicker grip, better trigger. More shots.

Allthough the AA dóes have advantages above the Tau as well: its alu, so no rust, iirc, the front sight exchangeable easier.
