I have to say anything Zooz that I have has been rock solid. Once I install them I've never had to touch it again. Their zwave implementation makes driver writing simple and they follow the standards closely (on the products I own).
I specifically would like to nominate the Zooz Zen16 Multirelay. I've installed it to control my garage doors and have never had an issue in the year or so its been installed. It just works and is really flexible in what it can do.
