there is no way to be sure with those inexpensive brands, it is always a lotto. but in this particular case, it is certainty 99,9% you will get new holder, they seem to stop making first gen holders
i stopped using all my oem holders and bands, i print my own, and i use 35-40mm bands. for d10-25 as well as zebralight and skilhunt.
if you can print, you can find stl in this thread, [Review] 77 Outdoors D25 Headlamp (18650) and it is tested and it works great, just print it on the side,
i also designed my own holder for d10-25, as well as zl h600. i have no way to post stl here, not i have acct at stl hosting sites, but if interested pm me i’ll email you stl.
btw, you can heat up 2nd gen holders grips and bend them in tiny bit, and it will hold just as good as 1st, i tried it and it worked great, using a construction heat gun, but i set it too high, and edges started bubbling, but it still held the light firm.
