Beautifully made, the narrowest tread cranks out there. They saved a 650B conversion I was doing where the BB was too low with wide tread cranks (which caused nasty pedal strikes). But be verrrrry careful when tightening the bolts. They are much smaller and less robust than standard chainring bolts. I have sheared the shoulder off of four of the nuts so far, not even using much force.
