OK let me be clear about something. I’m giving this 5 stars because — I guess — I have low expectations for shower mirrors and fogginess. It goes with the territory.It says fogless? well that’s a lie. HOWEVER when I do my standard anti-fog prevention measures this mirror stays fog free for much longer than my prior mirror. I had to get rid of my prior mirror because it was all crusty with hard water build up and would fog up within seconds no matter what I did to it. Here is my anti-fog ritual:Run it under the water for a bit. 10-20 seconds. This shouldn’t be a problem since you are already in the shower.Hang it up. It comes with a hookTake a SCANT amount of bar soap (But you can use shampoo/conditioner too) on your fingers and smear it all over the mirror.Shave. Try not to breathe on the mirror.So my old mirror would last seconds (Small exaggeration, maybe like 15 seconds) but this mirror is lasting like a solid minute or more (I actually don’t remember it fogging unless I did something like heavily breathe on it). It’s quite wide — maybe too wide — but you know just look at the posted dimensions. They didn’t lie about the size. So if you want something smaller get something smaller.The hook hangs well, this hangs well on the hook, honestly I think it’s great. You just have to get it out of your head that anything is inherently or natively ‘fogless’DEFINITELY worth the $9. I can’t believe I didn’t get this sooner… I’ve been suffering with my terrible mirror for 2 years… for what? to save $9? That’s ridiculous.This review was written for: 1Pcs Fogless Shower Mirror for Shaving Makeup, 9.45” x 7.87” Wall Hanging Shower Mirror with Adhesive Hook, Unbreakable Little Mirror for Bathroom, Bedroom and Dorm Locker
