I have the gemini duo on my bars and an older magicshine on the lid - two spares in a small backpack/on frame and a backup headlamp.
My friend runs the titan on his bars (that sets shrubs on fire at full power) and the duo on his helmet.
I've not had any issues with them so far - these are all recent models, but I really do make sure that I fully discharge and recharge after each ride - I'm not 100% sure if that's really necessary these days or a hold over from the older days of Li-Ion batteries.
Gemini's customer service has been excellent for buying spares and answering questions, Dunbar usually stock them so that's a good reason for me to buy them there and support an LBS with usually great pricing.
