$149 if I needed to rehab to be able to shoot again I would do it. For just practice it is a little too much, heck I can just walk outside to shoot so it isn't something I need.
Just ordered two of these for our shop, cool item to have at the bench to let customers try out a release, or if they have never used a release before and want to learn, or if they've never even shot a bow before... we get tons of kids in right now and its good to run through the motions with. At Least that's my hope. From a training aspect, I know $150 is a lot for what it is, a tool, but man looks like a sweet way to practice while watching BHOD in the living room lol "Couldn't think of a good Signature"
If I lived in town or could not shoot in my yard I would have one, bet with a d loop and a release and a peep it would let you work on target panic too.
