Great product, paired to several WA-361's, no issues, clear reception through all walls (block & frame) Haven't worked out max distance yet but 100' no problems. No interference in very unfriendly EMI environment.

Good sound, great price, responsive customer support, will buy more. WA-321 to five WA-361 being used for audio distribution to four powered monitors in a restaurant/bar and one to a DJ booth in the adjacent room, 40Ft. + brick. Still working now for 90+ days, 10hrs every day and made it through a tropical storm, only needed to be reset once since installed, really good for wireless. One unit was DOA, had to be active exchanged, 7 days, luckily one loudspeaker was still hard wired until the replacement came in. Buying a few extra units for backups.
