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)

Sorry for the headline, that was the best I could come up with for a one-liner.This vacuum is awful. It takes a long time to charge and has poor suction even once the battery is full.Inside the box, there was a green sticky goop substance that worked much better at cleaning the cat hair out of my keyboard than the vacuum itself did. It was only good for use one time though, because I had so much cat hair left in the keyboard, even after vacuuming until the battery was empty.The filter is pretty much useless. It's a piece of foam precariously suspended right inside the cannister, so when you open it to empty it, not only will the few contents fall all over you, but the filter will fall out with the trash.This was just, ugh, such an awful waste of money. Save your time and money and look elsewhere.Let me know if you find something better for cleaning keyboards because I really ought to clean mine at least once a week but haven't found anything effective that can do that.

Not enough suction power to remove thread and lint from my sewing machine! Works if you place the nozzle directly on the lint. If the nozzle is a 1/2 an inch away, it doesn't pick up anything.

It's alright, not as powerful as I'd hoped

Cheaply made product, thought it would replace canned air, boy was i wrong. You are better off with keyboard slime

This isn't the most powerful, it doesn't quite pick up everything in keyboard like I had hoped.

Good don’t feel the power strong enough but it did it job

Great little unit. Just what I needed for my model railway.

Honestly, you are better off buying a can of compressed air!!Completely INEFFECTIVE!!! - definitely NOT worth the price!!
