Terrific system
This works so much better than my old, previously, high end router. I had one of the ones with three external antennas, so I assumed that coverage of a single Deco M5 unit would be inferior (but overall better due to the mesh capability). I was very surprised to find that from the same location (in a closet), the Deco blew away my old router. It actually covered my house fairly well with a single unit. However, out on the front porch and down the steps, it still struggled.
I then added one of the remote units to my living room, near the front window. Now my porch, the steps and the sidewalk below are flooded with wifi. I used to have a problem when getting into my car, where maps or music wouldn't load, as my phone was still trying to use my wifi. I'd have to either switch it off or drive a block to get it to give up. Now it just works, so it took away that minor irritation.
I had been planning to use wired backhaul for the remote, but I ended up placing it somewhere I didn't have ethernet. After testing and finding that I'm easily getting 50-60 mbps in some of our previous dead zones, I don't see any need to run a new cable. The system seems smart enough to keep everyone on the main router, and only a couple of periphery, low-bandwidth devices are using the remote unit.
Lastly, I was very happy to find that these use only 4W per my kill-a-watt. Two of these are using slightly less power than my old Asus router.
