Wilko's Rotary Washing Lines

I don't know what it is, but rotary washing lines just seem to fall to bits or collapse at my house. I have bought a variety of washing lines from B & Q, Homebase, garden centres and all have busted in about four months. Some of these lines have cost up to £40 as well! What a rip off.

I stopped off at Wilko's and looked at their range. Not bad, unknown makes but look OK. So I bought one. It does not have the same height as the others so long ...
