VisibleDust Arctic Butterfly 724 Super Bright

Here’s an electric brush designed to attract dust away from your sensor via the wonders of static charge.

The brush’s ultra-fine bristles are attached to a rotating shaft driven by a pair of AAA batteries in the handle. Ten seconds of spinning prior to cleaning ejects dust from the brush, and, with the help of the fibres’ nano-coating, gives the bristles a static charge. Then, with the brush stationary again, you lightly drag it across your sensor to pick up any loose particles.

A pair of LEDs light the way. This is important because you don’t want the bristles to come into contact with areas surrounding the sensor, due to the risk of debris or mirror lubricant getting dragged onto the sensor.

Loose dust is picked up pretty well, but the brush doesn’t hold on to particles as reliably as the SpeckGrabber, making the high price hard to justify.

Pros Easy and fun to use; fairly effective for removing dust Cons Premium price, yet will only clean dry debris; no loupe We say A novel concept, but the high price is hard to justify Overall score
