FOUKUS 200000RPM Electric Compressed Air Duster: 2-in-1 Blower and Vacuum, Powerful Mini Blower, 10000mAh Cordless Air Duster

This duster works very well with 4 power settings and a battery level display from 0 to 100% which helps to know when to charge it more accurately. Though it seems fairly well built, I believe a big drop or fall will fatally damage it so I am very careful to always maintain a firm grip at all times and never place it where it may fall off a table or other surface. Using the single button is a little bit complex since you either have to press the button repeatedly to toggle the 4 power levels or press and hold to turn it off while on any power level. If you use it often, you can get used to it. The flashlight on the front looks like it may be helpful in low light situations. Press button: -twice quickly to turn battery display on/off -once for power level 1 (P1) -press a second time for P2 -third for P3 -fourth for P4 -fifth time for power OFF It has a vacuum attachment which should be useful (haven't used yet). I wish it had attachments to further narrow the output end to use the 'Bernoulli effect' for additionaly focused fast airflow. Even P4 will not match a spray duster, but this is good for blowing out an electric razor, blowing light dust off plastic or porous surfaces, and even some drying of wet surfaces.
