Anyone have an ATTACH-MATE?

[INDYFIGHTER]

Came across this thing shopping for wooden dummy alternatives. It looks pretty cool and I'd like to have one for my Wavemaster but I find only this one site offers them and I'm a little skeptical of the sites two gleaming reviews. Has anyone got one of these and if so how do you like it? Does anyone know anyone else selling them?
Thanks!
