Bests & Worsts Reviews from Amazon

I was very impressed with how well this cleaned down to the bottom of the keys. For the dust below the keys, only compressed gas will clean. This is no criticism of this gel product, simply a recommendation you buy it along with compressed gas. Examining the gel after I used it the first time revealed that it had captured more debris than I had noticed before using it --- and there was no visible debris left on my keyboard after using it. The lemon scent the gel leaves after cleaning is very pleasant and not strong and lasts about half an hour. If not for the understandable need for compressed air for computer keyboards, I would have given this five stars.
