Have used Petzl's for 20+ years, excellent product. More recently Black Diamond, so far I would say they have been excellent. Last year bought a couple of Nitecore rechargeable NU25's for use this past winter in the early morning and/or evening outside around my place. Used them for about an hour each day, usually 4-5 days a week. The rechargeable function is real handy, end of the day plug them in. They worked great, only one season but I'm impressed.
