swap the guts of your free lights?
my opinion:
fwiw, I found Banggood very easy to work with, and they have done right by me. They do ask for a video every time, but once they get it, they refund, and if the item is small, they let you keep it.
As Streamer reports, he has a free Tip that he still uses, despite its failings. Hard to complain about Free.
I also have a Free Astrolux M03, that unfortunately I do Not use, it flickers madly and I cant find low mode most of the time, so the refund was legit, and the freebie unfortunately, unuseable.
Seeing as they had given me a refund, I ordered an M02, which to my happy surprise, works very well.
In any case, specific to the Tip, if accidental activation is a dealbreaker, and youre out of patience trying the replacement approach, consider a refund and then order again separately. It is possible replacement lights come out of a different bag than new orders
Also, I bought a LAD instead of a Tip. The LAD has ZERO accidental activation issues. There are other differences between the two, for my needs the LAD is working out very well…
unfortunately Banggood does not over a deal on the LAD, if they did, I would not hesitate to order from them again.
fwiw, Im not affiliated, and they dont send me free stuff to review… just my experience and opinion… ymmv (hopefully not
