So I bought another A01 that just arrived today. It is definitely brighter than the original one. It still may not be 100 lumens, but it is at least as bright as my Fenix E05, which is close enough. I’m still not sure if I damaged the first one when taking it apart to fix the next-mode memory, though I did the same to the new one too.

As for the M01, I contacted the seller, sent them a video, and they said the light was broken, and they’d replace it. All I had to do was wait for the supplier to send them one, which would be in about two weeks. That was three weeks ago, and the seller is still looking into what is taking the supplier so long. I put in a claim with my credit card.
