I've been shaving in the shower for almost 20 years and this mirror works perfectly. Over a decade or so ago I purchased a shower tek mirror that circulated water around the back of the mirror to keep it from fogging (same basic principle to reduce fogging for temperature differences as this Shave Well) except it was flawed by the fact that the plastic arm (tubing) that holds the Shower Tek and circulates the water eventually failed after just a year or so. After that I realized I could just keep using the mirror but had to use RainX or I used toothpaste or other soap and the warm shower water to keep it fog free long enough to get a shave. Since the Shower Tek tubing arm broke years ago, I've been holding the mirror in one hand while shaving with the other. I've noticed over the years that shaving in the shower after washing my face with a good facial soap did not require shaving cream if the water was warm enough and I had a good razor. I don't rinse the facial soap off, I simply shave it off. So shaving while holding the mirror literally only takes 60 - 90 seconds.Fast forward 10+ years and my Shower Tek fell on the hard tile floor in the shower one too many times and a few weeks ago it cracked and shattered leaving glass shards on the floor of the shower while I was trying to shave. In my search to find a replacement mirror that wouldn't break the bank, would stay fog free for at least a few minutes, and would not shatter into pieces if I dropped it (water and soap = slippery in shower) I was fortunate enough to find this Shave Well Fog-Free mirror.Deluxe Shave Well Fog-free Shower Mirror - 33% Larger Than the Original Shave Well MirrorI see several 1 and 2 star reviews and I just can't wrap my head around those reviews. I am an experienced shower shaver for two decades. I have finally found the perfect shower mirror. It's small enough to hold in one hand while shaving (hanging or positioning any mirror in the shower doesn't give me enough light anywhere) which is perfect since you can move the mirror easily to see what needs to be shaved. Holding it also allows you to easily rinse the front and back to equalize the temperature to keep it fog free during your shave, and also allows a quick rinse in the shower (if necessary) when you rinse the razor.The last thing I do in the shower is shave so that my skin and the mirror have had time to warm up to get a good shave. I've found that the Shave Well mirror stays fog free for much longer than I need it. I have even attached several photos so you can see that my shower door is fogged but the mirror is not. That is after shaving and rinsing off and opening the shower door to get my phone to take the pictures.Anyone that says this mirror fogs up, either has it in the wrong place, did not prep it with toothpaste or facial soap, or hold it under warm water (front and back) long enough (I do it for about 30 seconds, 15 on each side). This is science people and it just plain works. You should also know that I accidently knocked the mirror off it's hook a couple days ago and it crashed to the floor. I'm glad it did not shatter, but it did land right on the bottom left corner and it did chip a tiny piece of the material (I seems to be some sort of plastic or lexan with a mirror coating). The mirror survived the fall with grace and while I have a small chip in the corner, it still stays fog free and I still get a great view of when I'm shaving in the shower.I'll be buying some of these for holiday gifts for my friends that have never experienced shower shaving and all of the benefits that go along with it. If you're at all curious or on the fence, I say take the plunge, you'll be glad you did.
