I got thisOXO Good Grips Electronics Cleaning Brush since I needed a better way to clean the keyboard of my computer, anApple MacBook Pro laptop. Because, while I useiKlear Spray and a soft cotton knit or flannel (since I usually HATE microfiber cleaning cloths as their texture is so weird & rough and often gets caught on the pads of my fingers or the palm[s] of my hands) scrap of cloth (usually a rag from worn-out old pajamas that were made into cutoffs) to wipe the screen, the mouse/trackpad and other areas, and that works very well, I've been finding it increasingly difficult to reach into the narrow spaces (like in/around/between the sides of the keys and the rest of the keyboard & other areas) with the just the cloth and spray. Although thisApple MacBook Pro is the FIRST Mac computer I've ever owned (though its not the first Apple product I've had -- I got an iPad Mini in 2012) it is ABSOLUTELY, POSITIVELY my FAVORITE computer. Since out of ALL the half-dozen, or dozen or so Windows PCs I've had, over the years (going all the way back to Windows 3.1 in the early 90's) it is HANDS-DOWN the BEST computer that I've ever had, I'm very careful (even go as far as to say, anal & obsessed) about keeping it clean & pristine, and running in new condition for as long as possible! So I was looking for a can of compressed air, a keyboard brush, or some other kind of device that could fit in (and clean out) the gaps between the keys and other small crevices. That was when I came across theOXO Good Grips Electronics Cleaning Brush -- and I'm glad I got it! Basically, theOXO Good Grips Electronics Cleaning Brush is a pen-like device that on one end, has a slim silicone wiper with a slanted/pointed tip and at the other end has a soft-bristle brush. After almost a month of having/using this item, on a nearly daily basis, I can say with certainty that BOTH parts (the silicone wiper AND the soft-bristle brush) are ESSENTIAL -- especially for cleaning Mac laptops, in which, as far as I can tell, the gaps between the keyboard keys & the laptop chassis are a lot more narrow & harder to clean out than any of my prior PC laptops (though in all fairness, my PC computers, lasted such a short time [usually around 2 years or less], and were so riddled with problems starting pretty much from Day 1, that I never really bothered to spend much time/energy cleaning the laptop, especially in/around/underneath the keyboard keys like I do with my MacBook Pro which has lasted 4 years as of this coming Christmas -- and is still going strong!) When I clean my laptop, which I usually do on a daily (or alternate/every-other-day) or weekly basis, I first turn theMacBook Pro upside down while open (meaning with the keyboard facing down) and VERY GENTLY tap on the bottom/back of the laptop to get out any stray dirt, crumbs, and/or lint, that might have gotten stuck inside/underneath the keyboard keys, before using the soft-bristle brush on this device, to sweep away whatever dust was loosened in the course of tapping it while holding it upside down. Then, I use the pointed tip of the silicone wiper to grab whatever dirt, crumbs, and/or lint that remain between the keyboard keys -- and finally, last but not least, I use a soft cotton knit or flannel cloth rag and theiKlear Spray to wipe down the screen, the mouse/trackpad, the laptop chassis and the keyboard. I don't usually wipe down the top (front) or bottom (back) of the laptop very often because its pretty much always covered by a hardshell protective case. Anyway, I've been using theOXO Good Grips Electronics Cleaning Brush for almost a month, and for the most part, it is a GREAT cleaning device. The silicone wiper (especially when using the pointed tip) is very flexible and TERRIFIC at being able to fit INSIDE the sides of the keys, and pick up dirt, lint, crumbs & other stuff. The silicone wiper also comes with a clear plastic cap to keep it clean & protect it from picking up dirt, crumbs, hairs, lint or whatever, when not in use. The soft-bristled brush is also pretty good, though its just a basic soft-bristle brush like any other out there, and nothing to really rave about -- at least not as much as the silicone wiper which is a real help in grabbing whatever dirt, crumbs, lint or whatever else finds its way into the keyboard keys. I love this device and really only have one quibble, which is not really a quibble actually. Its just that the silicone wiper is so GREAT at picking up stuff (dirt, lint, crumbs, etc.) that its necessary to WIPE THE WIPER several times while cleaning my keyboard because of all the gunk from underneath the keys that get stuck to it. That's the only real issue I have with this. I just wish there was a way to reduce the number of times necessary to wipe the silicone wiper clean. But I guess the only way to do that would be to make the wiper bigger, so that it can hold more gunk before needing to be wiped -- yet increasing the size of the silicone wiper would probably make it too big to fit into the narrow gaps around/inside the keys, which would totally defeat the purpose (for me anyway!) of getting this device. Other than that, this is a GREAT computer/electronics cleaner and I'm really glad I got it, and plan to continue using it to clean my laptop on a regular basis!! ★☆★☆★ 5 STARS!!!!
