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
Brilliant shower, excellent quality, performance & value for money. A great replacement for an existing shower.
