This aerolatte frother contains a motor that operates at a ‘dry’ rotation speed and torque that is specific to the function of foaming milk. Both components are made from food-approved 18/8 stainless steel. 
The steel used for the shaft is hardened and thickened in order to protect against bending and to increase robustness. 
The spiral whisking head is cut from a purpose-produced spring. The density and tightness of the coils promote effective frothing.
The aerolatte handle is made from moulded virgin ABS plastic.
The battery and motor contact plates are nickel-coated in order to prevent corrosion. Comes complete with two aerolatte-branded AA alkaline batteries that are pre-installed.
The batteries should be replaced when the motor noticeably slows and the shaft begins to wobble (after approximately 150 uses). Any equivalent alkaline batteries will be suitable.
