I think this was maybe a bigger deal back at CES but I'd never heard of it at the time. Its an interesting twist on rolling up a keyboard
Note I have no idea why its $20 on Amazon for Prime when its normally $120??!?!
But hey for that little I'd probably jump at it. For myself I need the function keys (dont let apple let you believe they aren't useful because for god sakes I need esc and F1-F22) so I can't really justify it.
But if function keys aren't a huge priority might be worth checking out if you have Amazon Prime. I mean $20 for a decent compact keyboard isn't a bad deal. If its bad heck its only $20
They have a Rolly2 that had an additional row for function keys and esc. Its pentagram shaped ratehr than square shaped. And somehow costs less than the Rolly1? That's super confusing.
