[EX Q]: I have very hard water where I live. I use this once or twice a week and it really helps remove the build up on my hair. I'll definitely keep using this.
[EX A]: positive

[EX Q]: Unit switches off whenever it feels like it. No matter how long you set the timer for, it will randomly just turn off and then yogurt cultures get cold. The dome is also shaped to have condensation drop into the center glass container. Pretty poor design. The rest of the condensation runs down the dome, and instead of draining into the base unit, it just runs onto your countertop. Can't wait to send it back !!
[EX A]: negative

[EX Q]: I love the quality of the product and the nice rain shower produced by it. Including a high-quality metal extender arm was a nice plus. I also bought a valve on Amazon that allows me to toggle between the fixed shower head and a handheld one-it also allows you to split the water stream. With this setup, it's like being on vacation at an expensive hotel. The shower head will require periodic cleaning to ensure that the water nozzels are not plugged, but that takes only a minute.
[EX A]:
positive
