That’s interesting, thanks. I a word and meant to ask which you use more, oops. The strap says that it works better on hard surfaces which makes me wonder about

That’s interesting, thanks. I a word and meant to ask which you use more, oops. The strap says that it works better on hard surfaces which makes me wonder about how it fares on say, a leg, stiff cushion, or things like that. Also if it’s not using an optical sensor, I wonder what happens when you try playing an instrument with it on. Might have to give it a try.
