Hi Vidas,

A few years ago, I bought a roll-up piano hoping that it would provide a means for me to practice on my airline trips. I desperately wanted to like it. But I HATED it! There was no tactile feel… No way to tell one key from the other. And the contacts didn’t work very well, so it was difficult to play the notes without tapping them pretty hard.

But maybe there has been progress in their construction? Which one did you buy? You must be somewhat pleased with it if you can get it to work well enough to make videos!
