I got this slick setup that says Savox. It stores then bits in the handle. BUT just like their servos they work great at first but then they start to suck.
It won't hold the bits tight anymore and the "lid" that keeps the other bits in is loose, turns and the bits fall out.
My mother in law got me the Reef’s one for my last birthday. I wanted it to toss in my lipo bag when I go to the local track just in case I need to fix something. So far it’s served it’s purpose just fine, but the tips do not have anywhere near the precision fit as much Vanquish hex drivers. Not that I was expecting that, but they’ll do okay for occasional use.
