RB accompanied his brother to visit a friend who made machines. When RB showed this friend his idea for the ball massager, the friend immediately recognized it to be similar to a ball bearing. RB was given one as a sample!
" it is an industrial product mainly used on production line to smooth
the moving of items. its call 牛眼轮 (bull's eye wheel) in chinese... "
RB tested it on his mother, and she liked it. First, they had a small talk...so they were on better terms again. Second, she may be biased, but RB and MM believe in their product!
