Fixed a slow filling toilet / and a continually filling toilet
Had a slow filling toilet, would take about 2 to 3 minutes to fill up the tank. Googled some solutions, overwhelmingly said replace this valve. I'm never lucky with repairs and wasn't expecting much. Followed a YouTube video to replace, easy peasy, took about 2 minutes in all. Old valve was split in two and completely useless. My toilet now fills in 20 seconds flat. It was the most satisfying bit of DIY I've done in a long time and the easiest. Valve works great and I have 4 more sitting in the cupboard in case the other toilet goes the same way. Cheap but very effective.Update : 18 months later the toilet continued to fill up after the valve should have closed the inlet. Replaced the valve again and it is filling quickly and stopping when it should now. So they are cheap and last about 18 months. I have 3 left now, should last me another 4 and a half years.

Fits, does the job and good value.
Good value for the number of items in the pack. First one failed but the second was fine. Fitted without any issues.

easy to fit and seemed to be swap-in compatible with the original siamp one I replaced
I've only needed one so far but considering the price was for 5x, I think it represents great value and I've got plenty of spares now even though this previous one lasted several years. This was a straightforward screw-off, replace, screw-on swap for me with the all original siamp dual flush fill part on my toilet - and it solved the problem of the noisy super slow refill, it was evident that the previous valve had split and worn a hole and this fixed it.

These are better quality
Tried others which didn't work. The white plastic insert is thicker than the cheaper ones and the seals are better.

OEM or better, gasket seals that worked a treat
My toilet suddenly with no notice, wouldn't fill up with water. After some research, I bought these gasket seals and fitting it was simple. Just close off water supply to the toilet cistern part unscrew the component and swap out the split gasket seal. Turn on water and jobs a good un!Good quality pack of 5 seals at a great price.Good quality rubber and plastic seals that match or exceed OEM one, I took out.

Came in a pack of 5 two of which didn’t seem to work when old ones in toilet cistern replaced with them but thankfully we had spares which seem to be doing the job
