Question: What are the colored, transparent looking thing on the pictures of this shower head?  Is that part of the shower head?  Does it adjust the flow?
Document: That was my experience trying to save water by installing this shower head. Not only does it use more water than my very old high-efficiency shower head, but the stream of water it emits is too strong. Water splashes over the shower curtains wetting an area outside the tub that I must then clean after showering. As there is no way to adjust the flow rate or dispersal pattern with this shower head, I had no recourse but to remove it and reinstall the old one.
This little thing is really amazing.I replaced both of my old &#34;full flow&#34; shower heads in two separate bathrooms. One, was with a low flow handheld shower available from a big box retailer, and the other was with the High Sierra. Not apples to apples, but the prices were similar as were the efficiency claims. The High Sierra considerably outperforms the wimpy standard head even though it uses less water.
I would highly recommend this shower head to anyone looking to save water, I have already order another for my guest bathroom !! !
It is also easy to adjust the position of the head. I made a point to reorder another shower head for my other bathroom. I would recommend this product.
This is great. I was looking for a shower that blasted water out. This one does. I used to have the rain shower head and it was useless. A perk is that this item is high efficiency as well.
The look is a tad institutional since it is about the same diameter as the shower arm itself. I would love it if the head was more traditional looking, with the option to go with the full blast setting or a more traditional spray. My wife doesn't want one in her bathroom because she thinks it is too powerful. It also is a bit loud when it comes on, and sounds almost like a train whistle.
No problem there. At any setting there is none of the "needle effect" commonly experienced with low-flow showerheads. Water delivery is satisfying and comfortable across the full range of handle settings, so I'm confident some serious savings are available with this thing.3. Noise. If it's any noisier than its predecessor, it isn't enough so to be bothersome at any setting.4. Draining. There's NO residual dripping after shutting it off. Clearly it empties instantly and completely.
Should have gotten this a long time ago - love it. Noisy & ugly, but I still love it.Just make sure you adjust the head away from the floor!
Another thing I hope they will improve one day is the aesthetics. It's not ugly, but I think they can do a better job to make it look more like a high-end shower head without compromising on the water savings.
This shower head has begun to have this annoying whistle when showering. Why is this happening and how can I get it to stop? Is there something I can adjust?Edit 6/26/2013. I am upgrading my rating to 5 stars. The company sent me 2 new shower heads to replace ones that I had with the annoying whistle under high water pressure. We had switched our heating system from oil to natural gas with the new system having higher water pressure which started the high pitched whistle.
Answer: yes
