I originally gave it 2 stars because of install difficulty. The auto install would not work, units had difficulty connecting to devices, etc. but after manually installing and submitting a complaint, I have had the opportunity to use it. Fantastic coverage, even outside. Very stable also. I originally purchased 3 satellites and it covers my almost 3,000 sq ft single story house AND ring cameras outside, and in out buildings. I pre-ordered another satellite to place in my separate garage/workshop which is about 50 yds from the house to get a better signal there. Well worth the money. But they need to fix the auto install function.
Bought this to reach about 100 feet from front of my house, through my detached garage to my separate shop on the far side of the garage. Worked great especially given signal had to pass through at least 8 walls on the way, half of which are old style lathe and plaster. Set up was very very simple via the app. Almost too easy. For some reason it didn't connect to my ISP so i started over and was successful. I'm pleased thus far with the product. My old Netgear Nighthawk router and Extender just seemed to quit reaching far enough over time. Sounds weird I know.
