Evening all

Two questions:

1. Do you use a mirror on your bike? I'm considering one for my commute as I can end up amongst quite a bit of traffic and feel it might benefit my awareness.

2. At the cycle show at the NEC in sept I saw a company marketing a mirror to be worn on the arm. Tried one on and really liked the concept but having searched the internet am struggling to find the company and their product. Anyone see this and can point me in the right direction?

Thanks, and happy cycling!
