Samsung Galaxy S9 Case, Transparent Crystal Clear Cover with Slim Silicone Rubber Bumper Frame and 360° Rotating Magnetic Finger Ring & Kickstand Compatible with Samsung Galaxy S894

I've been using these for 15 years in place of the lousy air switch most people use. I've probably put in at least 50 in the kitchens I've built and all my customers love them. I have 2 in my house. One for a gd, and one without the timer to control a light over the sink. It's waterproof so it's great on the counter top. Best to throw away the little plastic nut and washer and silacone it into place. I've only had one callback this way and it was easy to fix it.
