Beryllium driver... for 25 bucks? Call me skeptical.
Firstly, it's relatively rare, secondly, it's hard to isolate and refine, partly because thirdly, working with it is highly toxic, as in to a possibly life threatening degree.
It's been done, but at very high cost.
Looks like a nice product for $25 though. Maybe I'll try the iPhone one...
supposedly an alloy only, so very little actual if that's the case
