Too many gadgets claim to be revolutionary but Suri (it stands for sustainable rituals) has a good go at reinventing the electric toothbrush. The focus is sustainability, but it also feels as though every element of its design has been thought through anew.

One aspect of sustainability is the materials: Suri features an aluminium handle and plant-based heads (sustainably sourced cornflour with castor oil bristles). Another is minimising: it’s about one-third the size of standard electric toothbrushes, so it uses far less materials. Another is repairability: the body is designed to be easily opened, without the need for specialist tools. This allows for repair and also makes it easier to recycle at the end of its life. That’s a refreshing change when other brands make it almost impossible, for example, to replace a dying rechargeable battery, so otherwise working products get scrapped.

Unboxing is classy. The packaging is plastic-free, modern and sets...
