1) Firstly, no need to be confused about the packaging with the Tomo brand name on it; Tomo is a high grade German brand and Marcoware is the series name for this and other products in the same range.
2) A really good product; feels solid and heavy in the hands; excellent build quality.
3) Been using it more than a year and there is no rust/oxidation anywhere. As shiny and new as day one. However, please note that like everything in life, you have to take care of things for them to last. Clean it once in a while and most importantly, keep your bathroom dry; I always leave my bathroom door open for it to air and dry out; if your bathroom is always wet and humid, then any fitting will eventually start to rust/oxidise.
4) Love the easy to clean silicone nozzles which have not gotten blocked even with the very hard water in my area.
5) Looks great, performs great and I liked it so much that I replaced all my other bathroom fittings with the same brand.
6) Good pressure; but my building has a pressure pump so I'm not able to say whether this will work in homes/buildings without pressure pumps. But logically, it should, since most buildings have overhead water tanks.
7) You can read the other reviews too; this is a great product at a great price and I will not even bother looking at any other brand from now on; even if there's something better, I don't need to know; I'm super happy with this brand. I have their handheld shower heads and other fittings as well and those are equally brilliant. Bought this after a lot of research and happy to report that it was a most satisfying purchase; highly and heartily recommended.
