These have been installed for 3 months now with 0 outages or false reports. Bumped up to 5 stars since my previous (only) complaint hasn't caused any issues. I have the sensor and magnets spaced out much further than recommended to keep them super sensitive to door positioning. No issues yet.
My worries of someone leaving the door just a little cracked are somewhat fixed by my locks; they attempt an auto-lock 3 times, but if it can't latch properly it stays unlocked and notifies me, so I'll at least be aware of a partially-closed door.
I did have some apps on my Smart Things sending push messages about the doors being left open or shutting off my thermostats for the same reason for a while, but looking at my log, the sensors were reporting properly; my auto door locks worked fine and the door sensor logs were accurate 100% of the time. Smart Things cloud errors might be to blame, but regardless the sensors have worked without fail.
Work well, easy to pair, came with white and brown covers. Magnet reaches pretty far. Only negative (and this is with any sort of magnetic sensor, I'd imagine) is you can get a false close status if the door is almost closed.
The only downside with this sensor is that it is large when you put it on the door frame (or window frame). Also, depending on the door, it may not screw in properly (I learned this the hard way with two french doors I have. But, luckily, the product comes with 2 3M double sided tape pads and it looks like my door/window sensors won't be falling off any time soon.
Overall, it's a great purchase for a simple functionality. To tell if the door/window was opened or closed. It does the job well (just make sure you configure notifications on your respective Z-Wave hub to display the information when you want it to). Also, at the price point when I purchased it, it's still cheaper than other Z-Wave devices out in the market. This is a recommended buy!
But then randomly they'll just work fine. The light flashes briefly when the door is opened/closed, and updates it's status correctly to the hub.
