I just received my HAP-Z1ES a couple of days ago and love it. Oddly it came with the latest software installed and with a 2018/19 build date. I guess they are still making the unit. Hopefully, that means more updates are coming. Also note, the prices seem to be coming down a bit. I picked up my new, but "open box", unit from Amazon for $1200. Please let me know where you go for usage tips from other users. Thanks, J
