Fluidmaster Side-Entry Fill Valve Euro 3/8" is rated 4.6 out of 5 by 16.
Rated 5 out of 5 by from Good bit of kit Well made quality bit of kit. Found it easy to fit and once on works perfectly. Biggest problem was getting the old fitting off. Found out that most of the pipes in the house are 1/2 inch but the feed to the cistern is 3/8 inch. As always no issue taking the wrong size kit back and Screwfix replaced it with the 3/8 inch unit.

Rated 5 out of 5 by from Couldn't believe how quiet... The old Torbec valve had started to bang when the cistern was full, so I read the reviews on Screwfix and decided to take a chance on this Fluidmaster one. It took just 5 minutes to fit and adjust. I still cannot get over the uncanny quietness now when the cistern fills. I was expecting a slight noise when the valve turns off, as reported by one or two reviewers of the 1/2 inch version, but no, nothing. I'm very pleased with my purchase. I can't really give a fair rating on reliability, as I've only just fitted it.

Rated 5 out of 5 by from A feelgood story. Loo seems happy with it. My tenants are happy with it. My wife was happy paying for it. I was happy putting it in. Screwfix was happy selling it. A happy end.

Rated 5 out of 5 by from Does what it says on the box Have used fluidmaster products before so think the extra cost is worthwhile. Fitted it to an overseas property where the water is not hard (desalinated from sea). Have given it 4 stars for reliabilty only due to the fact that it will take some time to see if the desalinated water will have any effect on the valve. If fluidmaster reduced the price these valves would fly off the shelves. As I`m sure many other would go to them as first choice if they were cheaper.

Rated 1 out of 5 by from Have hard water? Don't buy one Not impressed, had one fitted for 18 months & it keeps failing. The blue float on the side sticks, it did it in its first few weeks, then settled down but now it does it constantly causing my water tank to overflow. This is bad design in my opinion, the water comes out of the top and dribbles down the side of the whole unit, so after 18 months in a fairly hard water area, this thing is coated with scale, it's presumably this that makes the float stick. At £18 it's the most expensive inlet valve I've ever bought and the fastest to fail. I won't be touching Fluidmaster again ..

Rated 5 out of 5 by from Fluidmaster side entry valve I always use Fluidmaster, although more expensive than others, they are very reliable and robust, false economy buying cheaper brands.
