Does this Bootstar Chip work?

[Clairvoyant]

First thing to say is: I´M A NOOB!
sry that I didn´t take hours of time to look through all threads before posting, but searching the forum for Bootstar didn´t give a result.
Now my questions:
Does anyone own a Bootstar and can tell me, how good this thing works? Are there any problems? How is it installed?
I´d really appreciate info on this, because this chip isn´t the cheapest and I want to know if the performance equals its cost.

Thx
