Question: How do you change the water pressure settings? I try to turn it butI don't want to break it. Please help ;-)
Document: I have hard water that was drying my hair and skin out, someone suggested a filtered shower head. I  found the Negative Ion shower head ordered it immediately and it arrived within just a few days. It does not come with a hose, however I had one and it fit so that made no difference to me. So I hooked it up and used it immediately, it was like it gave my water some pressure. The settings are great I felt the difference immediately and it felt heavenly.
I give this product a 4 out of 5, because it works well, I didn't lose water pressure, it has several spray settings, looks great and my skin feels super soft. I did end up purchasing the Waterstick shower water softener because I enjoy the slickness of softened water and the added benefit of luxuriously soft hair; but this shower head is a keeper! If you can't afford a whole house softener, or the Waterstick, this is the next best thing!
I'm not really crazy about any of the stream settings but they're not awful.-I use the outer ring setting as it seems to provide the most coverage and pressure. The setting started out with a steady stream from each nozzle in a straight, uniform direction when I first started using it. Now, there appears to be a v-shaped void where a couple/few of the nozzles shoot at an angle different from the rest.
I was excited to try this out and I'm glad I did. I could tell the water was soft the very first time. We'll worth it!
Pros:8 Spray Settings.Cons:The product doesn't really filter the water, I haven't felt or seen any difference in the water at all.
This one does still have considerable pressure - not like those super water saver ones, thankfully, so it's still pretty decent. I think the pressure is satisfactorily forceful yet safe and decent to use for all ages and for pets too.All in all, it's a decent purchase. I did a lot of reading of reviews on many different models before deciding on this one. For the price and features, this was what I thought was the best option.
I live in DC and the water here is very tough on your head and skin. I could see a definite change in my skin and hair as soon as I purchased this ion shower head and would recommend it to people with sensitive skins or prone to allergies.I didn't rate it higher because I think the materials with which is made are really cheap, basically just plastic, which can be dented or broken very easily. Other than this, this product does exactly what it says it does
We have VERY hard well water. And have been dealing with it for the 4 years we have been living here. It's hard on your skin, and your hair never feels clean. THIS THING WORKS! Your skin feels softer, your hair cleaner, and you actually want to take more showers than you really need.....
Please note that you will need a hose and bracket. I just went to local hardware store and bought a cheaper shower head that included both those items in it. Worked perfect and took around 5 minutes to install.
This shower head is amazing! I have already had numerous comments on my hair looking shinier and brighter. For sure my hair is much more manageable. In addition, I feel as if my pores are tighter on my face. My scalp feels healthy and not as dry. In addition, my skin feels softer. All of this and it hasn't even been a week! I hope it continues to work or that I maintain the success. Good price and you never have to change the filter.
Answer: yes
