Looking at the loudness metre, they’re about the same. But this one has lower pitch compared to the one in FunSR1 2.0 due to the bearings.
It has mount and twist. You can see that in my review on the FunSR1 2.0: 🌀 [Review] FUN SR1 2.0: Stroker With a Twist!
The default mount looks like this:
Though personally I prefer to mount it to a magic arm, clamp the arm to the desk and then rest the device on my lap. This is basically how I use my handy hands-free. There is several 1/4 screw holes on the FunSR1 2.0 you can use with the magic arm.
I don’t get what it means by “handy compatibility”.
