The Circulate 2 is nearly rectangular, sloping in barely in the direction of the highest the place the strap connects. The bottom of the gadget is coated in a sturdy plastic, which shelters the USB-C port and charging pins on the underside.
Should you haven’t seen it earlier than, the entrance of the gadget is slightly uncommon. The highest half is roofed in small holes that enable air to circulate via to the sensors beneath. The decrease half is devoted to a capacitive button. When pressed, the present air pollution stage is displayed utilizing coloured LEDs that encompass the button. The LEDs function on a visitors gentle system, starting from inexperienced for low air pollution, to pink for extreme ranges.
Circulate 2 Battery Life
