I can confirm this as well with my production run C01s. When poking with a needle the white stuff feels hard and solid.
When comparing a Fenix E01 with a Sofirn C01 the potting material looks similarly white.
Did Sofirn ever communicate what material they actually use for potting the driver?
Some kind of epoxy, or some other material?
There is of course a large overlap between harvested ideas and what people want. And communication with the chinese manufacturers will always be difficult, for numerous reasons. I can’t exclude stealing ideas without giving back proportionally as a motivation for contact but as far as I was involved with Thorfire and Sofirn, there’s more going on, not just profit, it is combined with a will to make a good product too.
Received my three samples 3200K today. Very nice, good anodisation, I can see the potting over the side of the driver and trough the hole of the PCB, it seem very robust. I can’t (at the moment) pull out the driver. The clip is very strong, and it is not dificult to remove it.
Very good keychain, very good purchase, it’s a shame it’s not easily modifiable
For what it’s worth, I ordered Nov 10 and tracking shows not even leaving China yet. If tracking is correct, that’s 18 days of sittin….:weary:

After the comments by you and djozz I looked closely at the clip on the production C01.
So regarding communication: it seems Sofirn listened to feedback by djozz and improved its design.
However I would still advice to remove it the correct way: at the ring where it attaches to the flashlight, either by using a small screwdriver or by using both thumbs to push it off at the open side of the attachment ring.
And not like I did by using the “tip” of the clip as a lever to push it off (learning moment…) :person_facepalming:
I wish they (or someone) would make inexpensive* addon clips like those made for the 4sevensPrion or the Solarforce lights —attached by dropping a complete ring over the tailcap threads.
Thanks for pointing this out. I edited the Specifications post accordingly.
Perhaps in the future Sofirn might share with us the potting material of the C01.
I had some trouble opening the test videos uploaded by Sofirn to YOUKU.
Great videos so I reposted them on Youtube, and added the links to the Opening Post.
