Hello, how difficult is it to clean under the keys? Can the keys be popped off and snapped back in similar to a regular keyboard? I'm a bit of a clean freak and I'd love to be able to vacuum under them one in a while.

On an SC17 or SC15, I would recommend against removing the keys. They plastic clasps and tabs were meant for a strong installation but will break if removed multiple times (or if you are unlucky, the first time). This is the case with most laptop keyboards. I have used compressed air on laptop keyboards for years, it will easily push out anything that is not sticky.

Maybe blow it off once a week or month to avoid any buildup.I never liked the cold can air on warm electronics,I use a dry air compressor.
