Looks beautiful, but it’s junk. It is non-standard so replacing it, if it goes bad will be a horrendous job. You will need to tear open your entire wall to replace it. 

It does not have integral stops (a code requirement) so if you ever have to work on the cartridge (replace a washer), you will either need an ugly access panel in the adjacent room or you will need to turn off the water to the house, and drain the lines. 

There is not an easy guide for installing with the correct depth (like the depth plates that come with standard hardware. You will have to carefully calculate. 

Additionally, NONE of the plates seal against water. Water WILL get behind every plate and rot your walls and grow mold, unless you put an ugly bead of caulk around every plate. 

In hindsight, spending triple on a similar-look Moen or other standard hardware would have been a much wiser purchase.
