Unifi UAP-AC-HD are they worth it?
The newest AUP-AC-HD are definately better than most of the other series if you are using it in a business environment woth more than 1000sq ft.
I guess at home they would also work as well, but may be overkill. These will push out 1733 of bandwidth and have 4×4 MIMO for grouping user signals together. If you are have latencey or slowness with your current setup replace with these and you will lower your frustrations.
The price on these seems high, but you will not beleive the difference it will make.
