Learning to play the piano is always going to be difficult, but it is more difficult than it needs to be because the same music has different fingers for each of the 12 keys. With this keyboard the fingering is the same for every key, making it easier to learn and play.
Piano is limited because one hand can span little more than an octave. This would allow much more.
This model had 192 keys. I'd guess that was redundancy in order to avoid boundary conditions. It is said to have been a quality instrument at a reasonable price, but (predictably) it didn't catch on. The company gave up in 2014.
