Suri 2 Sonic Toothbrush Review: 90-Day Battery, Aluminium Build

What Is the Suri 2?

The Suri 2 is a sonic electric toothbrush designed around two principles that most competitors de-prioritise: longevity and sustainability. The body is milled aluminium — the same material decision as a premium phone or laptop — rather than the injection-moulded plastic that defines most toothbrushes, including expensive ones. The brush heads use bio-based nylon derived from castor oil plants, which requires significantly less fossil-fuel input than standard nylon. At £104.99 and 4.6 stars from 2,162 buyers, it has found its audience.

Battery Life

The headline feature is 90 days per charge. At twice-daily brushing for 2 minutes each time, that is 180 sessions from a single charge via the travel case. For context, a Philips Sonicare DiamondClean needs charging every two weeks; an Oral-B iO every week. The 90-day window changes the relationship with the brush — it becomes a stable object in the bathroom rather than something that needs weekly attention.

Brushing Performance

The sonic motor delivers 31,000 movements per minute, in line with premium category benchmarks. Five modes — Clean, White, Sensitive, Gum Care, and Polish — cover the main use cases. The pressure sensor detects overbrushing and changes the vibration pattern — a tactile signal that does not require checking a display. Two-minute timer with 30-second quadrant pulses is standard for the category.

Sustainability

The bio-based brush heads and aluminium body are the differentiating argument for environmentally conscious buyers. Replacement heads are ordered directly from Suri rather than being available on Amazon, which adds a step but keeps the supply chain controlled. The travel case charger is a design choice that works well in practice but means the toothbrush cannot be charged from a standard USB-C cable.

Verdict

For buyers who want a premium toothbrush that takes sustainability seriously, the Suri 2 is the strongest option available. The 90-day battery is genuinely life-improving, and the aluminium build quality is immediately apparent. The price is honest for what it is.

Rating: 4.6/5 — The premium toothbrush for buyers who think about materials.
