8 months later - the follow up:
It's like I knew I would be coming back to them. I wound up ripping 15 switches from another brand out of my house to replace with Zooz. Agnes (@agnes.zooz) helped me identify Zooz's recommendations for all my switches. I've had them installed for 2 days now with ZERO issues so far. It's z-wave, so I am sure I have a problem or two on the horizon, but I am a little shocked at how well everything is running, and how well everything set up right out of the box. I have been struggling with the other brand's switches that I removed for 8 or 9 months, and NEVER had working 100%. And I'm not new to this. This is the second house that I set up a fairly involved Z-wave network in. Granted I have some non-standard configurations (who in home automation doesn't), but the Zooz switches are robust enough to handle it, while the other brand just simply wasn't.
So Zooz guided me with their recommendations for my application***, and provided 16 new switches along with some reconfiguration recommendations. They even made some concessions to me when I told them about concerns I had, having been burned by buying 15 very expensive switches from the other company (that I am now stuck with). Basically, they promised to stick with me, and work with me to try to figure out any problems I might have. And in the end, if we couldn't make it work, they would take them back. But I wasn't going to burn through the return period with several days between communication trying to troubleshoot. Zooz is awesome. They have an awesome product, killer support, and excellent communication. I just can't get over how easily it all went and how quickly everything was not only up and working, but working right.
We prepared by planning which switches would be installed where. I sent Agnes a spreadsheet with switch locations, single/3-way, bulbs brands and types, power draw, etc. She discussed them with her team, identified that the garage lights and laundry room lights drew too much power, and made recommendations. I replaced my aging florescent wraparounds with LED wraparound lighting (super easy - and huge lighting improvement using less power), and ordered the Zooz switches. When it all came in, I had the whole thing done in one night after work. This went super smooth.
If you're thinking about investing in new Z-wave light switches I highly recommend Zooz. If you're reading this and six months or more has passed, reply and ask me if I am still happy with this purchase.
On to the next project - under-counter RGBW.

*** If you about to start a new Z-wave project using Zooz, it would behoove you to contact them for a recommendation first - even for one switch. For 13 of my switches, I was going to order the Zen27s but the better switch for my appliciation was the Zen22s. The best of us can benefit from the recommendations of those with experience.
