I got one in my black Discmania Mystery Box. I've been a bit skeptical of the activity and the quality of discs. I decided to give this one a go and it has not disappointed me!
The rim is a bit shallower than most drivers which is great for someone with small hands. And the rim width is similar to a 9 or 10 speed driver. This is a very friendly disc for all levels of play. The one I received in my mystery box is more flat that the standard runs which offer more dome.
A surprisingly good disc!
