For me that was short-winded! However, it was oblique, so I'll recap in more detail:
I have some experience of these wastes, and it strikes me that they're far too complicated for what is a very simple function. Don't even get me started on pop-up wastes....
If you want something that doesn't have a chain, and isn't a pop-up, then for only a little more expense I can recommend a type that is elegant in looks and in construction. If interested then let me know and I'll dig out the company name.
And as for Screwfix? Hmm. Best not go there, both in the legal sense and as a customer. Oh alright then. Allegedly, many consider it to be nothing more than a shed that sells shoddy shed-type things cheaply, and then makes it inconvenient and expensive to return faulty goods. If you want to run down the business of your local merchants such that they might not be there when you really need them to be, continue using the Internet for procuring plumbing fittings.
