Belts extremely short

The belts are extremely short, it is absolutely impossible that an adult Central Europeans can support the part on the back. The man pictured sitting probably in the advertising on the Ryanair airplane seat cross-legged?

The accessories are displayed on the overview screen 3 times, but of course (as in the schriftl. Description) only once here.

The processing makes a good impression, unfortunately stinks part as a chemistry major accident.

I bought it mainly because all functional parts are made of plastic and I, etc. in brass pipes with other manufacturers already had corrosion, if you do not nachspülte thorough enough.

I have not yet tested the function. First, I will new (long) straps mount it.
