The Brush Head You'll Buy Again Matters More Than the Handle

These brushes ask for different daily habits: one follows each tooth with a small round head; the other glides a slim sonic head along the gumline. The refill you buy later matters too.

30-second verdict

Choose the Oral-B iO2 if a compact round head, three gentle-to-daily settings and an included travel case suit the way you brush. Choose the Philips Sonicare 5300 if you prefer a slim sonic head, two intensity choices, a head-change reminder and the maker's claimed 21-day runtime. Both checked UK offers were new, in stock, sold and shipped by Amazon, and had working purchase controls. The brush-head systems are different: buy iO heads for the Oral-B and compatible Sonicare click-on heads for the Philips. Neither maker's promotional cleaning percentage proves a head-to-head winner.

A small round head, three brushing settings and a case in the boxPick 1 · Oral-B

iO2 Night Black with Travel Case

iO2 · Black · Handle + Case · ASIN B0F24ZVQSL

£39.97 new offer checked 24 Sep 2026

The iO2's round head is guided from tooth to tooth. Extra-gentle, gentle and daily-clean settings change the feel without an app or display. When excess pressure is detected, the brush slows and shows red; its timer prompts a change of brushing area every 30 seconds. The checked Black Handle + Case bundle includes one iO head, charger and travel case. Feedback on that exact option mentions comfortable use and easy charging, but also a fiddly case. Keep future costs in mind: this handle uses iO replacement heads, not standard Oral-B heads. The checked new offer was sold and shipped by Amazon.

A slim sonic head and longer claimed time between chargesPick 2 · Philips Sonicare

Series 5300 Black

HX7101/01 · [New] Black · ASIN B0DCGK4MT7

£59.99 new offer checked 24 Sep 2026

The 5300 uses a slim sonic head and one clean mode with low and high intensity. Its pressure sensor responds with a pulse/vibration, while BrushPacer and Smartimer guide a two-minute routine. Philips states up to 21 days of regular brushing per charge and a two-year limited warranty; those are maker specifications, not our runtime test. The checked box includes one W2 Optimal White click-on head and charger, with no travel case confirmed. Feedback for this exact black style mentions that the high-pitched sonic sensation takes getting used to, alongside appreciation for the two intensities. The checked new offer was sold and shipped by Amazon.

What we researched

The daily difference is the head you guide around your mouth and the replacement-head system you keep buying into. The checked Oral-B listing showed 3K+ bought in the past month and 1,920 global ratings; the Philips showed 2K+ and 2,550. Those are current signals for the selected Amazon listings, not UK market share or category rankings. Global rating pools may combine options. Neither brush was tested by us.

Key findings

The head shape is the lasting choice

The Oral-B asks you to linger on individual teeth with a small round head. The Philips uses a slim sonic head. The right motion is the one you will use carefully twice a day; maker plaque percentages do not establish which of these exact offers performs better for you.

High

Do not mix up the refill families

Oral-B iO heads are a separate system from standard Oral-B heads. The Philips accepts compatible Sonicare click-on heads. Both checked boxes start with one head, so compare the ongoing refill costs and the fit of your preferred head before buying a handle.

High

The travel trade-off is concrete

The checked iO2 bundle includes a case, although matching-option feedback finds it fiddly to pack. Philips claims longer runtime, up to 21 days under its stated use pattern, but the checked box did not confirm a case. A claimed battery figure is not a guarantee for each user.
