Thanks for the review giorgoskok. Good to see you got the reflector removed from the pill. Was it hard?

It didn’t have any glue , i used a wrench to get some grip on the pill , and it was done in seconds .

Edit: i don’t know the exact name of the tool i used (lol), closest i could find is Monkey wrench

Seems you have covered all the bases with this review. Well done. Considering other C8’s have loose interchangeable reflectors AFAIK, and this one has a drop-in, is it possible to share some more (comparable white wall) beamshots?

I always think long and hard before I say something really stupid.

Unfortunately white wall beamshots are hard to get right , but i will give it a try . Anyway , i can ensure you it has a perfect beam pattern .
