I have a set now on my worn xtreme pole. Previously it was prone to collapsing, difficult to match the tension of the clamps in differing clamping points and well, a pain in the backside in use.
The new clamps take a little time to adapt to - they tend to flop when undone but in use they are superb. Sprung loaded with wider opening clamp bodies they seem much smoother too. If your pole is new then there is no need to upgrade - just wait for it to wear then change. Very similar to the old ones at first glance but totally different in reality.
Well done Gardiners!
