Well I have been using Tir2 now for about a month,no problems. Have come up with this for those who didn't order the TrackHat. I know, I know I have a hat and it works well. Just thought of this last night and figured I'd pass it along.
Took a piece of 1/2in o.d. rubber hose,cut it lengthwise,added a large "dot" that came with the unit and now have a universal dot...
Just thought you all may want another idea for the reflective material
