II recently went to a bike show and bought an old version Blackburn Flea for $5. The guy at the booth assured me it would work. I got it home and found out it wouldn't. I contacted Blackburn and they sent me a new, new version Flea for free.
How nice of them.
I really like this light and I think it is every bit as good as my Cygolight Hotshot, and it is much easier to charge. I think I prefer it for that reason alone.
It is also easier to mount.
That is all.
