If you've ever wanted one of these to tinker with or test and see how hard they are to destroy here's your chance. Bought this at a bargain bin and was unable to reset it. It uses the "eSmartLock" app. I was able to pair to the lock after about five attempts, but it says I need to ask the administrator for permission to access it, and obviously I have no idea who that is. I guess on the plus side it's not simple to hack, but on the downside it's kind of useless if you can't unlock it. ...unless you just want it to see how it stands up to bolt cutters ;)
