This product is a game-changer for computer maintenance. As a result of my tests, I determined that the Elephant Particles Shavings work wonders for any dusty or dirty computer. Not ONLY is it effective, but it's also rechargeable, which saves money in the long run .The only downside is that it can be a bit noisy, but that's a small price to pay for a smoothly running computer. Overall, a must-have for any computer owner..See full review
