One of the most interesting products in this niche is the roll up keyboard. There are more manufacturers that have a variant to this product, but I think Wisedeal made the best one. It’s very convenient to store and extremely easy to carry. Whenever you’re in the mood to play it you just roll it out and enjoy it. It has a built-in speaker, that will not sound like a sound system, but considering how portable this device is, it’s pretty good. This roll up keyboard has 100 rhythm options and 128 tone functions. Again, pretty impressive.
All in all it’s a fun musical instrument, but it can’t be really compared to proper digital pianos. It’s more like an interesting device that will bring a lot of joy and laughter to the family. If you would like to learn to play the piano, though, I would advise looking up a proper digital piano.
