A Good Replacement and Simple to Install
My old one failed. I'm not plumber, just an everyday DIY enthusiast. Be aware that you may well need to buy the accompanying float ball. The instructions were quite sufficient to make this a simple job. I just needed an adjustable spanner and a plier wrench. Some adjustment is needed to get the fill level correct, but it's simple enough. Perhaps 15 minutes in total.

Only needed one small part to.fix the flush on my toilet, couldn't purchase separately so this was the cheapest option.
