Blackburn has a similar design. I think Blackburn bought the design from Rhode Gear.
The ones I have use circular mirrors, not the oval. I've used several of the oval mirrors, and the ball joint tends to not stay in place and then eventually fail in fatigue after several years, unlike the simple hinges typically used for circular mirrors.
Of course, Rhode Gear and Blackburn are just sub-brands of Bell Sports these days, so it's not surprising they're sharing branding.
