I have that same headlamp, and use it a lot. been banging it around since last year, used it many many times for over night trips, and it never failed me once. Same goes for the DX80 i have. always worked perfectly. While some have had bad luck with them, all my Imalent lights work great. In my instance, every Sunwayman light i ever bought/had all failed or arrived DOA. The only Acebeam (Supbeam) i had so far was the X40, which was a total failure with the unbalanced charging fiasco, then its magnetic ring started to give problems. Right now that light is in pieces in a junk box. I may look into the X80GT sometime in the future though when i can afford it.
