But if the door opens towards you, it's really hard to pull on the handle with your forearm and this would provide something to hook your arm around for leverage.
And at a cost of €40 per pair it's a no-no. I think they will gain more from the free promo they will get from media/clicks than actual sells of the specific handle.
It probably cost less than a dollar to print these.
EDIT: Yep. Just added one to the slicer. $1 if you are paying about $25 per filament, which is on the expensive side. It would cost me about half as much.
