Well? Quark is dead. You can't lick it no more and you can't Quark the zombies no more bro.
Back to Nitecore, I remember those early days when I got myself some D10 and EX10. Oh I was a big fan of Nitecore then. They are pretty nice lights and at that time Nitecore was just Nitecore, not under Sysmax.
Got quite a few pieces from 4sevens then and I really liked them a lot. Occasionally I will clean and oil the piston to ensure it is problem free. Had one with an XR-E Q5 in my pocket for a few years and the grey anodizing was all worn till it looks like silver. Sold or gifted them all away when LED technology progresses over the years, but the wife still have one till today. She uses it almost everyday and hers just recently stopped working last month, or the month before. All in all, it lasted about 9 years of frequent usage. Dropped, kicked upon, and submerged. Pretty impressive I would say.
Years later, under Sysmax, they offered a revamp of the D10, the D11. Purchased a D11.2 and it is just horrible. The lowest output is too bright, and there is a horrible parasitic drain which drains up my battery in a matter of hours even when it is off. The D11.2 felt warm throughout while in my pocket. Gave up on it and exchanged it for another Nitecore light, the IFE1. Well, it is problematic as well so changed it for another Nitecore model again, and again, and then again, and was never happy. There was always one problem after another. I decided to give up on Nitecore once and for all.
3 years back when they came up with the TM26, I was kind of drawn to the switch and the UI it has and I decided I will give Nitecore another chance so I bought it. I was impressed with the TM26, even till today. I liked it since day one of ownership.
Then I thought I will give the EA8w a try since I have tons of Eneloop lying around. It worked great for awhile and died for no reasons.
I just recently bought a TM16 and I hope it survive. If this TM16 fail me, Nitecore would be completely out of my books.
