Wow, that's a really great advertising video. They must have invested a lot in a marketing consultancy. If you compare this to some terrible Roland marketing...

Exactly for that reason demomstrated in the video i recently bought a roland go piano... maybe i should have waited? Portabillity seems to be a trend among the youth... who would hvae ever guessed this.. we have come a long way considering my youth when there where home organs and real piano’s.

This Dexibell Vivo S1 looks to me closer to Roland RD-64 rather than to "GO Piano". Go Piano is indeed lightweight and affordable; others are more of borderline in terms of weight and price.

I like this promotional video. Also interesting that the camera they used (Panasonic GH5) is not some ultra-expensive professional stuff, nor it's a super-heavy and large, so I guess it's a new way of doing things - mobile and for reasonable money.
