I got these after moving into my new house and they were incredibly easy to set up. I had everything up and running in about 5 minutes. They have great coverage as well. We have zero dead zones in the house, and I've never had a device get dropped. I wouldn't suggest using the app for managing them though. It's far easier to just use a web browser.
Up until now, Logitech Harmony was pretty much your top contender in the universal remote world. It was well but having to plug the remote to your Mac/PC to update is an extra step that is undesirable. Also the product itself is fugly. This is where Neeo excel. Neeo uses a 2 pat sytem, the brain and the Neeo remote. All remote update is done via WiFi instantly. Setting the remote with the Neeo mobile app is so much easier. Also, Neeo is beautifully design. They care about aesthetic which I really appreciate. Their aesthetic reference classic European design like Baum, B&O, B&W, Meis Van der Rhoe and Vitra.
