First off, I officially hate these guys because I had this idea about a month before they released their product (it happened with the AxSak, too, dammit!). Every other stabilizer system uses a pre-loaded spring (either under compression or tension) to get their force discontinuity. This thing, however, uses a magnet, hidden inside the red housing.

 

Verdict:

Ease of Installation: Looks really easy to install. Basically, one screw and you're pretty much done.

Ease of Adjustment: From the looks of it, you cannot adjust the pre-tension. The magnet is what it is. If you want stiffer or lighter stabilization, I think you're kinda screwed. On the other hand, the position adjustment looks really easy... just one screw (like the Floyd-Rose one). Like the Floyd and the TremSetter, I'm a little turned off by the fact that you can't easily go back to a previous setting (if you try to improve the adjustment and end up making it worse).

Effectiveness: Dunno. Haven't tried one. ????

Cost: $45 isn't bad... if that's really what they go for. Where do you buy these things?

Overall: Based upon reviews I've read, I'll give it three stars for now. I might increase that once I get one in my hands and I can try it out.
