I purchased the black model. It is very well made and the strength of the flow of water was surprisingly strong. I am only at 5 out of 10 on strength and it's more than enough for me. I love the additional heads and they work very well. You can use whatever mix you want. I use mouth wash and water (warm). I can't not use it. Every day i use this. Love it. The only negative is it's a tad bit loud, but not ridiculously loud. So worth it.
