Visual Note Music Learning Device G Type

I bought this one as a gift for a friend who just started learning and also as a trial to see if i shall get some for students but it turns out to he very buggy on the software side. Not playing in sync, disappearing tabs, connectivity issues etc. The tech support is doing a great job but the product is just not ready yet. I need it to work reliably. At least at this moment it doesn't. So i wouldnt recommend it but i still see potential and hope for updates.

The product was bought as a gift for our kid. It is easy to apply and fun to play with.
Very enjoyable way of learning.
