Good chair - but buy better without armrests

Sufficient much told to the chair.
I would just like to confirm once again that the 40 can be saved for the armrests and dear to the offer (here on Amazon) without precisely this should grab.
Why?

Because these are mounted on the one hand only by a screw. While this holds, but is deficient. That would be but for the price still acceptable in my opinion.
BUT: In a relatively normal size of 185cm (male) are the armrests in the highest position simply does not reach. Locker 5-10cm air.

Let's see what the customer says, if I want to send only the armrests back.
