Aftermarket center armrest

On Ebay you can find 2 types aftermarket armrests for the Peugeot 107.
They cost about half the price you would pay at your dealer.
And they both claim that it will perfectly fit the Peugeot 107.

Type 1


Type 2


I think I want a center armrest (Type 2) but I'm not sure about it.
Is an armrest a comfortable option? How about shifting gear with it?

Does anybody have any experience with it?
And how about the quality of the armrest?
