I could be wrong as well. But stihl makes a saw that you pull the start cord almost effortlessly for 2 or so times, press a button and it spins the motor.
I say heck no. More junk to fail. Keep your saw maintained and only use rec gas with good mix. No cheap stuff and most saws start easy.
Yeah I've seen that one. Looked like a gimmick to me, but I never really looked into that much.
