Love this thing! I’m extremely happy with this choice. There’s not a ton of info on it, so I learned a lot from my install that I’ll put out here, in no particular order. Hope this is helpful.
1. It comes in two boxes. One (mixing valves) came from USA quickly. The shower head itself came from China in a week.
2. It takes 4 half-inch pipes to feed the head, then another for the wand. I have 3/4” water lines to the master bath, I can generally run 2 functions at once without losing too much pressure. 3 or more and it gets weak. But obviously the mist uses much less water than the waterfalls.
3. The included wire from the shower head LEDs to the wall-mount light switch is 12ft. The included switch is black, my wife hated it. I bought a white one from Amazon for about $25. https://www.amazon.com/gp/aw/d/B07T8HJYBY?psc=1&ref=ppx_pop_mob_b_asin_title
The switch is also not a standard American size, I needed to buy an Asian electric box in order to mount it to the wall. Search for an 86mm box.
4. There’s a lot of steam. Get a good vent fan for the room. And paint your ceiling high-gloss so you can wipe it.
