The basics, quickly
Four brush heads, black colourway, compatible with most Oral-B electric toothbrushes. Under eight quid for the pack. That works out to two pounds a head, which is frankly decent for Cross Action compatibility. The black finish is a minor thing, but it does look less grim after a few weeks of use compared to white ones, which tend to show every bit of toothpaste residue if you're not obsessive about rinsing.
Who this actually makes sense for
If you already own an Oral-B handle, this is a no-brainer restock. Dentists usually say replace heads every three months, so a four-pack covers you for a year. One per person in a couple, six months sorted. Straightforward maths.
Personally, I always end up buying these last minute when a head is visibly frayed and I've been ignoring it for a month. Having a stash removes that particular low-grade guilt entirely.
The honest reservation: these aren't the fancy round-up-of-every-feature heads. No pressure sensor indicator, no fancy bristle technology beyond the cross action angle. If you want Oral-B's top-tier heads, look at the iO series replacements instead. But for everyday cleaning, these do the job properly.
The community verdict
The HotUKDeals heat on this one is real, over 1500 degrees. That kind of traction usually means people have actually bought and found it worth flagging, not just upvoted because the photo looked nice. Stock moving fast at this price seems likely, so if you're already thinking about it, probably don't leave it sitting in a tab.
