I have one MR40Z in service for 7-8 months. Initially, I had trouble pairing using LR and just went with mesh (as documented here).
It has the simple job of toggling on a lamp when I need to video conference in my home office. For that, it is a decent tool. The plastic is glossy and shows fingerprints readily. I have not compared to the Zooz flavor, so I can't say if it is better/worse. I do rather like the rechargeable feature on the Zooz, though.
