I've had this airer for a year or so, and when I first unpacked it, I wasn't at all sure it would stand the test of time as the individual rungs are very slim/narrow.
The rungs are fine, but the wheels are useless.
After a year, 2 of the wheels came off. I put them back on, and they immediately dropped out of their sockets! The problem with the wheels, is that they fit into plastic sockets, and the sockets distort after a while. If only the sockets were metal, it would still be going strong.
I'm continuing to use the airer without the wheels on, but I'm looking for a new tower airer asap. I wouldn't buy another of this brand.
