The Fogless Shower Mirror by ToiletTree is the Best Fogless Mirror on the Market. I have been waiting to write this review since I bought it July 5, 2010 on Amazon.com, but to give my review more credence I waited the recommended 30 days. First, this fogless mirror works perfectly. I have yet to see any fog develop on the mirror what so ever. It is lightweight plastic or similar. The mirror appears to be glass, but it is a high quality reflection without distortion (just a little). It is perfect for any task that you might perform in or out of the shower, but I use it to shave. If you have never shaved in the shower, I urge you to buy this mirror and start shaving in the shower for a closer and more comfortable shaving experience. It uses adhesives to attach to a shower wall. Follow the instructions carefully to mount the mirror mount to the shower wall. Once the mirror is mounted it is permanent, but you can adjust the viewing angle up or down. You must fill the reservoir with warm or hot water in order for the mirror to remain fogless. That is easy to do. Why I like this type of fogless mirror is the placement of the mirror in relationship to the shower stream. Other mirrors that attach to the shower/water pipe have you standing in and facing the shower stream. That type of mirror allows the water to splash in your face and eyes. The ToiletTree Fogless Shower Mirror allows you to mount the mirror anywhere in the shower that you please so pick your spot carefully as it is permanently mounted.
