I had it out, "in use" on a short ride I got out for yesterday....did not bother to turn it in when I got on the trails...It got smacked by all sorts of things and held up just fine.
I had to break myself of the habit of turning my whole head around to see what was behind me. I can now actually look in mirror and see what is there.
Discount?? I think its priced pretty damn fair. Maybe a $5 discount if you buy a set.....I was happy buying one and paying $25...and I am a cheap bastid. LOL
Krabill: You might try dipping the ball end on some rubber tool handle compound. Might work.
