I received my Y25 today. Number 357. Put it together and shot some arrows. It is heavy, noisey as all get out, quite slow and now where near as accurate as my TenPoints, plus the trigger is lousy.
With 410gr Goldtips, 2" blasers the best I get is 291FPS. So much for the advertised 330FPS! 
Best group I can get is 2&1/2 inches at 20yds off a rock solid bench. (Same arrows shot from my TenPoints group under 3/4"inch if I want to ruin a few arrows) It makes all kind of ratlling noises , worse than a Cyclone, trigger has more creep and travel than a cheap foriegn rifle trigger. Final let-off is rough and hard.
The one positive thing is it's a pretty good looking crossbow!
