I purchased this unit to expand a current Orbi system with two units. We have a 500m2 property and the two units provided coverage, but the WIFI was slower in parts of the home. With the third unit I have been able to place them so that the whole home receives good WIFI coverage. Recommended system for fast WIFI over a larger area. Is reasonably expensive, but we use the WIFI every day so can justify the cost (and it keeps the kids happy).
