Excellent product. I felt I bought more than what I need for my requirement, 600sqft house with three floors. I kept one in 1st floor and other one in 2nd floor connected with ethernet backhaul.

Even on second floor i am now getting full speed. I would suggest this even you can extend budget as it is complete value for money and future proof too due to wifi 6e.
