I gave one an honest try and it didn't work out for me.......I probably just got a lemon but the horizontal dovetail cracked on me and the rest was drifting from day to day and my POI was moving around and I thought I was going nuts. [:-] took me a few days to realize that I didn't forget how to shoot.
That and the launcher "Whine" drove me nuts. Its a weird tuning fork sort of sound when you draw an arrow across it to full draw. (I have even heard it on hunting videos where they were shooting a Rip Cord)
So those 2 things combined with the underlying paranoia of picturing that raised launcher not dropping at the moment of truth on a huge buck packed it in for me.
I'm sure it's working great for lots of guys but I sent mine back and moved on.
