I've had one for over 12 years--one of the plastic pieces that threads onto the shower arm broke a couple of months ago. I bought a plastic replacement one locally but you can order a metal one from the company. I have the original Rinse Ace not the pet version. I don't use it all that often but would not be without one. They're great. Here is a link that might be useful: Rinse Ace

One thing you might like to consider is what I did: no wall-mount shower head at all and only the hand-held shower head on a bar. This would be a way to save money, too. I had this at my old house in both the master bath and the kids' bath, and I did it again in my new house when we renovated. I really like having the hand-held for washing the walls, not just for the weekly scrub, but for rinsing after every use to get the soap off and prevent scum from forming. I also like it for washing intimate areas and the kids' hair, and it's nice to have the shower head height adjustable on a bar if any children will ever use your shower. I have never missed having a regular wall-mount shower head. I have used Grohe and Hansgrohe shower heads. One warning about the rain shower head is that some people have complained that they have insufficient force to rinse out thick hair. I have never used one, but you might look on the forum.

I need some input from anyone who might have this valve connected to a shower head and a hand-held shower wand. I wanted two single function valves; plumber convinced my husband that two would not be necessary; the Moentrol valve was fine he said. Well, it is not fine! The shower-head seems to have enough pressure...the hand-held is so weak that it was a waste of $ putting it in. Do I have a faulty valve or is weak pressure the norm with a multi-function hand-held wand and this valve. I have the same wand upstairs on its own valve; water pressure is excellent. i am NOT happy! I knew what I wanted...there would have been no issues! If low hand-held pressure is the norm, am I out of line to ask him to share in the expense of putting it on its own valve? *cross-posted in plumbing

Although, we are re-doing a bathtub/shower, and I am replacing it with showerhead, handshower and tub spout, and had to get all the pieces separately (didn't care for the Symmons styles). We are going to use a delta pressure balanced valve (but it has separate handles on one valve, one for water volume and one for temperature), and then a diverter (to go to either tub, shower, or handheld). The rest of the parts are going to be Grohe, but they are all from different style lines (yeah, it sounds like Frankenstein but I don't think it will look that bad).
