    I purchased one for each window and external door of my house. I have found them to be quite efficient. There was a problem with the last one I installed, it kept going offline. I was short one sensor and ordered it later. When it arrived, I added it to the last window. Now the other window rarely goes offline and the last window goes offline quite a bit. They do go back online on their own. Overall, I am satisfied.

    Sensors work great and seem to be of good quality. If they could slim them down in next version would be great but there are many more thicker ones out there as of now and the ring alarm is great.
