Can anybody give me any first hand information/opinions about the blackburn flea?

From another thread:

I think the Blackburn Flea set are great for everyday/pub/commute.

Velcro fastening (which doesn't slip), as well as the ability to attach rear to pocket/bag, etc. Nice and quick to remove and can be shoved into pocket when bike locked up.
Tiny but very, very bright. They don't take batteries, but instead are rechargeable off most batteries I believe (Only use rechargeable AA and AAA so far...).
They also don't look like complete shit, so they don't spoil the look of my fixie wixie.
I can't stand the crappy plastic CatEye mounts so I wanted something with no wanky special plastic/rubber fitting.

Also I believe they do a USB chargable set now.
