A little awkward.

For someone who still had no quick release, it is an improvement certainly. Impractical I find the Mini Castle, what we need to perform cumbersome and from below through a hole provided. The 3 mm lock sheet provides for a bolt cutter or a small hacksaw really no obstacle. The locking of the locking lever is mounted so unhappy that you have only 2 cm air between the bumper and the lock button. This would not be so serious if you do not pull out the knob would make a quarter turn and then the existing spring ensures that the pins are pulled into the intended recess.
