ECHTPower Keyboard Cleaner, USB Cordless Vacuum Cleaner, Powerful Rechargeable Mini Vacuum Cleaner Portable Vacuum Cleaner for PC, Hairs, Crumbs, Scrap, Pet House and Laptop (Built in Li-Battery)

I have been using this for a month now and I gotta say that with the brush extension it really does pick up dust or other particulates that may be in a keyboard. Even use it to remove dust from my rig. I have not tried using it for a prolong amount of time because just logically it will burn out if you are not careful enough. For a quick and easy cleanup, and if you're like me you do it weekly, I recommend this product.

I actually bought this to use in cleaning my gecko’s droppings. It has a strong suction and it is not too loud. It’s a great buy, especially for the price.

I raise monarchs, and I use this vacuum to suck up caterpillar poo (frass) from the tent bottom. Works perfectly! Quiet, easy to empty, sufficient suction (enough to vac the poo, but not so much that I'm worried about suctioning the tent materials to the nozzle or sucking up unsuspecting caterpillars). Exactly as expected and came charged right out of the box.

This thing is the most useless piece of garbage that I have ever purchased.Utterly worthless. Don't even think about it.

This thing has next to NO suction whatsoever. We fully charged the thing and it still wouldn't suck up any crumbs from my son's keyboard. I am so disappointed.

This unit works great to suck up loose ballast from track and turnouts, clean up excess static grass and associated debris. Dusts roads and parking lots that attract dust over time.

Not effective for what I needed. Not enough suction.

Not very good suction. Wanted it to vacuum up small leaves from behind a planter.
