"Great buy"
I have looked for one of these for years and am delighted! The construction is robust and it is easy to use. Whilst I agree that the instructions are not very clear, we did not experience the previous reviewer's problems with bad fitting, however, thanks to the previous reviewer's comments to which we referred, we had no trouble in assembly. TIP 1: The grub screws secure the joint in the handle. TIP 2: You have to squeeze the red trigger in order to fit the handle and extension. TIP 3: The two items which appear in step 4 are the split pins which secure the base. GREAT BUY!
