I’ve owned this lock for about 3 months now. I’ve read a lot of reviews, most negative. Most problems can be eliminated by redownloading the app. Setting up the app and calibration properly is crucial. I initial lve had most of the same problems, but after re-reading the instructions, and recalibrating the devices properly, i’ve gotten it to work 100% of the time as advertised. Just disappointed that there isn’t a Apple Watch app or I would give it 5 stars.
