I have a bunch of mag lights, but their warrantee is crap, they want more to ship them back, than the light costs.
I have two that are junk status now, that were not that old, damn Duracell batteries leaked and ruined them.
I have since switched to everedy battery's and have had no issues.
I have also had good luck with the cheap harbor freight lights, their quantum series lights just plain work and are cheap.
