Machine Rest?

[HardBall]

Has anyone tried Caldwell's "HAMMR" rest? It's a good deal cheaper than a Ransom.

I ordered one from Midway but it'll be some weeks before I can get some range time with it.

I've always thought of one but keep spending my money on bullets.
How about a range report when you use it?
Thanks
