Pros
Pro Going for distance
This device has twice the range(120ft) of a traditional router(60ft) while offering up to 5x's the connection speed at the same distances. The software and companion app help you place the devices in the best locations for signal strength, allowing you to play video games in your treehouse with the main router in the basement.
Cons
Con It is not perfect
This product boasts some of the best features on the market, but its not perfect. There are still some reported issues with WiFi connections to Xbox's and old iPhone models. Will this be solved? Yes, wait for an update from eero. Users have reported that the only times this issue was apparent was when the individuals residence was 3000+ sq. ft with multiple stories.
