I've had a Flash & Flare on my commuter for as long as they've been around (5, 6 years?). Good bit of kit, and have easily paid for themselves compared to the Cateye and Smart kit which lasted about 9 months.
Anyway, the plastic lens housing has started to break up where it screws into the ally body, so I phoned Exposure to see if that was avilable as a spare part. "Give us your address and I'll bung a couple in the post". I'd have happily paid for them, but nope, FoC.
