Fluidmaster Side-Entry Fill Valve ½" is rated 4.5 out of 5 by 125.
Rated 5 out of 5 by from Super fast fill up I found this fill valve super easy to install, and set up, great water level adjustment, runs very quiet, and is a fast fill. Overall very pleased and most importantly, the client was happy.

Rated 4 out of 5 by from So far so good This was very simple and quick to fit with the clear instructions provided. Much better than the Flodisasta it replaced, which failed after less than 1 year. It's also so quiet that I cannot hear the cistern filling. Only time will tell if it lasts. My only gripe is that the whole thing twists on its axis at the inlet pipe after it has been tightened. I'm not sure if this is to allow easy, tool-free adjustment of the float's position, but it it seems odd that it can easily be moved by hand.

Rated 5 out of 5 by from Toilet fill valve Very easy to install, instructions could be a bit simpler perhaps with a diagram. Only just fitted (20 mins ) so don't know about reliability yet but as it has spare washers would seem that the manufacturer expect it to last.

Rated 5 out of 5 by from easy fitting. easy and quick to fit. Turn off the water, undo the old ball valve, screw on the new unit, turn the water back on. It makes a change to find a 5 minute job only takes 5 minutes and the new valve is almost silent.

Rated 5 out of 5 by from Simple to install Nice and easy to fit. Good quality and value for money. Most importantly it does the job! I fitted it to my concealed cistern that didn't have room for a large unit, this fitted perfectly.

Rated 5 out of 5 by from Price, quality, reliability. Well made item which is VERY easy to fit and adjust. Screwfix also sell an equivalent for about half the price but this isn't exactly expensive so why risk the cheaper non-branded one?
