Update: I've been using it without a case for almost 12 months and I find it as new as the day I received it. It's been on planes, trains, cars, boats, beds, bars and beaches; no stain on the case or the switch. I recently removed the case to see if there is any dust or dirt inside the case. Nothing, snug fit and no debris. Despite the slight increase in the size of the switch, it's worth the compromise - it still fits easily in my beautiful WaterField case. 10/10 still. Original: The cover is tight and fits the hand very well. The cutouts are perfect and the overall measurements are slim but comforting. For a sub-$20 accessory, this is an easy pick. Good buy.
