I’ve had a bright orange A01 for 6 months now and it’s performed flawlessly. I’d order more in a heartbeat if needed. I hang mine on my standard neck lanyard, run it on Eneloops (get some good run times out of them) and find it perfect for EDC use.
One modification I did which improved the light for my use was the addition of some clear PVC tube around the waist of the light. Cut to length, heated in boiling water and then slid on with some soap, it has shrunk into place and gives my teeth something soft to bite into when I want my hands free. It also really does help my fingers grip too the barrel too, and you can also slide the PVC down over the end to give yourself a much better tail-standing ability.
I’ll add that since I thought of the tube trick, I have modded my Olight i3S similarly. I do enjoy chip-free teeth . I suspect there are several lights out there that would like the PVC tube treatment
PS: before anyone asks, I can’t remember what size tube it is, sorry - easy enough in a store to try a few until you find one that is hard to get on - that’s the one you want as with some hot water and soap it will slide on easily.
