The product came in good, as expected, and was priced very competitively. I have used Bristan showers before and found them to be reliable, even though some parts can be scarce, e.g. cartridges no longer available. My last recessed Bristan shower lasted for over 10 years.
After having a poor-quality product installed and used for a few years, I finally took the opportunity to upgrade to a better unit. I needed a vertical unit with two outlets, and this exactly fits the bill. I also prioritised the need for it to be a good brand, and I was not disappointed by this Bristan unit. It looks great, feels solidly made and has actually allowed us to change the temperature when taking a shower - not just crazy hot or freezing cold. I would definitely recommend it.
The valve works as predicted to equalise the pressures. There is some noise but not a problem
