It does what it’s supposed to do and we’ll, for the price tho I think you could find better options and there is a lot of liquid on the brush I’m not to sure if it’s safe for your computer.So much better than antibacterial wipes! The bristles easily get between and around the individual keys.This is a super simple concept, but amazingly awesome! I work from home and used it right away on my keyboard and it’s so fresh and so clean!This was so easy to use! The keys on my board had some built up after so much use and with this cleaner it helped take the grime off. It does not use a lot of the cleaner so it will last me a while. Worth the money spent.This is actually a really great product. You flip it upside down so the cleaning solution (70% isopropyl alcohol and 30% water) gets on the soft bristles of the brush, then you unscrew the brush, turn off your keyboard, and go over your keyboard in circular motions.It works well; cleans really quickly and dries quick. The bristles are long enough to get in between all the keys and soft enough that I'm not afraid of it damaging anything. Much better than those cold air cans, which means I actually use it often.Amazing customer service. First product received was damaged. They quickly responded and made it right. Very happy with the product. I’d you are like me and live on your computer some days the keyboard gets pretty nasty this is a great cleanerBristles are too short, doesn't work for me. It doesnt reach the bottom of the keyboard between the keys, if only it was a few mm longer on the bristles....Not eat to use.
