Good but not the best

I have used finger trainers for a while and this one it's good but not the best in my opinion.

Let's start with the good point:

It's very well built and return a general feeling of solidity.

The grip of the keys is good.

And the cons:

The resistence adjustment works in a misterious way, i tried to go down in order to increase it gradually but it seems to me that each keys has a different 0

It makes some strage noise while used.

all considered it's sufficient but you can find a better one if you want.
