I've dealt with Brinyte via Alibaba (for example) and Aliexpress. My first experience was with Mary and she was very nice. It seemed sketchy the way I dealt with them via Alibaba and sending money - but it worked out. I mention the experience at the end of the DIV05 review.
Now I know a little of the management personnel. Recently they've ask me to review a dive light for them. But so far I've declined. In a way that's good because I don't have to feel inclined to give a positive review.
