My install for 2 Hoppers and 2 Joeys was completed today in under 3 hours. We had zero issues. He didn't know about doing a factory reset in the Hoppers when using a duo node. Thanks goodness for these forums. I informed him about it first thing and everything went smoothly. I came from a 922 and 2 722 setup. I love how much the Hopper resembles the 922. I'm not missing anything! FWIW the lack of OTA isn't a real issue since PTAT is available.
