Just thought i would update after just over a week clamps are great no probs at all .
But just to note in relation to some lads having to adjust clamps a few times a day , If the clamp flops open and rotates slightly one way and this happens with the lever arm rotating in the same direction over the course of a day.
And you dont rotate the lever arm back over this will result in the user effectively loosening the clamp , once you get the knack of using the new clamps they are problem free . Mike
