We compared two battery-powered handheld milk frothers: the Zulay Kitchen Milk Boss and the Aerolatte.

What we looked at

Stated speed, what liquids they can be used with, build materials, guarantee, and price.

The verdict

If you want the lower price on a frother backed by a lifetime guarantee against rusting or breaking, the Zulay Milk Boss is the value pick, at £7.99. If you would rather pay £11.58 more for a frother whose listing states it will froth milk in 20 seconds or less and can also be used for soups, sauces and meringues, the Aerolatte is the more established option, at £19.57.
