I bought them it is easy to pop out the inserts for the qr and use a 12mm axle just wish they hade a 10mm axle adapter so i could use a Hadley axle.
They are stiff, light and just look awesome. i used an Atomlab 12-10mm reducer axle to fit them on my 09 Gruitr. Went from 32lbs with Atomlab pimplites to 29.11lbs and that is with tubes. If i used the qr and tubeless it would be even lighter.
