I take contrast showers on a nearly daily basis. For those who don't know what those are, it's when you alternate between hot as you can stand (2-4 minutes) and cold as you can stand (20 sec up to a minute), usually about 4 to six rotations. I usually like to do this until I start to sweat (around the 4th or 5th rotation). This is a fantastic immune booster and is also great for killing the onset of flu or cold or decreasing its duration as well. So, what's any of this got to do with this clock?I like to time my rotations but it's a pain to do so when your smart watch's face turns off and is sporadic about turning on at the flick of the wrist. So I looked for a shower clock. Even though this has a stop watch, you don't even need to use it because this clock also has a seconds counter as a part of its standard very easy to read (even when steamed up) face. The suction to the glass is easy to secure and is unmovable, keeping the clock put since being installed a couple of months ago. If you need a good, functional shower clock, this is a solid choice
