## Description

Stens replacement parts have become a favorite among lawn and landscape professionals thanks to exceptional performance.

Review: No more foggy mirrors! - Works great, easy to install, will probably buy another for the other mirror. It doesn't come with a plug, so it either needs to be hard wired, or buy a plug to add to the end of the cord. If your plugging it in, I would recommend buying a humidistat outlet so that it automatically turns on once the room hits a preset humidity level.
Review: After 8 months still working great, easy installation - Works great and was easy to install with basic electrical knowledge. Fair warning though: what started as a Christmas gift for my wife somehow turned into a full bathroom remodel—new faucet, fixtures, paint, the works. This thing cost me several weekend golf rounds, but the bathroom looks great. Highly recommend… just protect your tee times!

### ⭐⭐⭐⭐⭐ After 8 months still working great, easy installation

### ⭐⭐⭐⭐⭐ Works well
*by D***M on June 29, 2023*

We were hoping for a video for installation but couldn't find one. The written instructions that came with it, though, were fairly easy to use. It suggested mounting the defogger at 6'6" which wasn't going to happen in our bathroom, but we did install it fairly high on the mirror. We wired it to the vanity light, which is the easiest thing to do. If we were remodeling or building, we would have installed a separate switch. However, we didn't have the option. It works really well. We purchased the smallest size and our mirror was at least 6" wider and longer than the defogger. But it defogs the whole mirror except for a very small border around the bottom and the sides. We are really pleased with this. Just a note that we did get a new framed mirror and hung it on a z bar, which makes all this possible. You really can't attach it to a flat mirror that is screwed to the wall with brackets.
