No different than the world of other cheap build consumer electronics. Remember the life cycle of this stuff is short…say 3 years or so. The original indoor and XT hardware as well as old sync modules are at end of life. I fully expect to read soon about them failing left and right.
Cell phones, tablets, digital picture frames, gps, Chromebooks, cheap laptops, wifi smart devices, the list goes on and on. After 3 years, you’re on life support.
