Yes, ridden it lots. I´ve got the top of the range carbon bling machine. It´s 24lbs but has been thrown down mountains all year with no problems. I wrote a review on the basqueMTB website, some thoughts on it really. In summary, it´s absolutely great.
Be careful with sizing, they size up small. I´m on a M but really need a Large. Pete Scullion is reviewing one for Wideopen so watch out for that. We did a big trip with them in the high Pyrenees with a few journalists last year, pretty extreme stuff, especially for a 140mm trail bike, and they loved the bike.
Happy to answer questions on the bike.
