Our take
Same 104 ink as the multipack, just the black bottle on its own. With over 11,000 reviews at 4.8★ it's one of the most-bought printer supplies on Amazon UK, which tells you how many EcoTanks are out there. Buy one when your black tank drops below the lower line; the colours will last two or three black refills.

Genuine vs compatible — which should you buy?
Genuine cartridges cost more per page but carry the maker's warranty, hit the quoted page yield reliably, and never trip firmware "unrecognised cartridge" blocks.
Compatible (third-party) cartridges are typically 40–70% cheaper. Quality is fine from reputable sellers, but yields are optimistic, colour accuracy varies, and some brands (HP with HP+ in particular) actively block them. For a mono laser printing text, compatibles are usually the sensible buy; for colour or warranty-critical kit, stay genuine.
