The idea is sound, but unfortunately, Ketter have neglected important needs, like providing a hinge that is suitable for the item.
The left-hand hinge snapped easily.
This is the second Ketter product I have had problems with, a drawer set from Argos had 3 of 4 castors break when wheeling the assembled item across a carpet, replaced by 4 superior castors from Screwfix.
Two bad products from Ketter, I decided to purchase a large wooden shed in preference to a Ketter one.
Not a seller problem, the seller can only offer a product that Ketter supplies.
No more Ketter plastic items for me !
