Cooper S BBR conversion

[vantage4]

Does anyone have any first hand experience of the 307BHP+brakes conversions made on a few Cooper S's about 3 years back by Brodie Brittan? I have been offered a very low mileage one and while keen to have it for a bit of fun am wary that it may be an explosion waiting to happen. I've read the August 05 EVO article about them but while it raves about them it doesn't tell you much about pitfalls of ownership, obviously!
Thanks!
