If you are looking for something to help your keyboard work better ( due to crumbs, dirt, or animal fur) this product wont help all that much. Some of my keys on my keyboard weren't working properly so I tried to use the key lift and hand blower. The key remover does not work at all and the blower works as good as a babys' nose squeegy . I will say that the blower works on pet hair that is on the keyboard but not in creases of the keys. Lastly, the brush is just the same type of brush used for womans blush. I tried to use it on my keyboard and it did absolutely nothing besides push the dog hair into the key creases.
