For the price of 165, it is a real opportunity for someone who wants 8 octaves.
The keys, although plastic, are very reliable and the construction is impeccable.
Do not expect them to be the same as a piano, but their springs are very good and they have some weight in terms of feel.
In terms of sensitivity, they are excellent.
At first, the feeling may seem strange for someone who is used to a classical piano, but after 5-10 minutes, you can play comfortably.
They do not have much noise. I would dare to say that they are quite quiet compared to the rest of the series. Solid construction.
The free applications that are included are very good and many.
Overall, I think it is the best available.

The only negative thing I can find is that it does not have many buttons other than the very basic ones.
