If you’re like me, you see this gizmo and gotta to wonder, what the hey? Well, it is a replacement for your blower bulb, it’s that simple. Charged by a simple USBc cable, this battery-operated blower (sensor screen in the photo above) replaces your old blower bulb. It works, and does a good job blowing off dust from the sensor. Works well even in high humidity. It’s physically small, and even sounds kinda cool. And if the $99 price works for your budget, I highly recommend it. Then, on the other hand, that old blower bulb works too.
