Soft, and provides decent amount of filtered air. Great design for a cheap alternative.

Phenomenal job getting dust off of dial faces and cases. Plastic tip does not mar surface finishes on cases and dial faces.

A bit to hard to squeeze multiple times, really gives your hand and forearm a workout (that’s a good thing, depends on how you feel about it), but it works.

Old school squeeze emits a push of air to dust off my new MacBook Air M2 satisfactorily.; works as advertised; reasonably priced.

I have a coffee grinder that retains a lot of grinds (an Ascaso i-mini) and I modded it to be a single dose grinder. So it has a 33mm OD/30mm ID aluminum tube instead of a hopper. This dust blower fits perfectly on top of the tube. It blows an adequate amount of air to expel a decent amount of grinds (and the nozzle is helpful to blow up the grind chute to loosen a lot of grinds). But I still need to work out some kinks before it'll expel all of them. But it was a good purchase and I'm happy I got it.

I needed a replacement air duster and this works great. Its light weight and fits in a bag or pocket better than my old one. It has less moving parts, so when it drops nothing breaks. Its easier on my hands when using, so less hand cramping. I have used it on vacuums, keyboards, computers, etc. Overall its a good device.

I mean, it's fun and it works what more is there to say?

This product simply doesn't work. It has a hole manufactured in the bulb that releases all the air it could provide.
