This is excellent for the price. The only minor gripe is that the knobs could do with an additional grub screw or a slightly longer threaded screw to stop them spinning. I fixed the problem by using a rubber O ring to create some extra tension.
The water on works with a great positive action and the flow rate is good, It maintains the water temp with no issues. I had no issues in fitting the unit but there was no clamp as I had with the old unit
We bought this to replace another shower which had been replaced twice but never worked. This matched the cut out in the tiles and matched our taps etc. The installation was straightforward but more importantly the performance is fantastic with no adjustment of factory settings required. Wish we had found this sooner and not paid twice to a well known bathroom supplier. This is highly recommended.
