Hi, I've just bought one of these second hand (the old blue ones) and the lift is really stuck. I have read this is a fault but its ridiculous, I have to force it to even move it either way. Its going to drive my easily-frustrated-two year old twins mad!
Is there a trick or something I don't know about (don't have the instructions). Or is it a dud? Or are they all this bad?
TIA
