We've had this for almost 2 months now. Really helped us giving the knowledge/empower our 3 years old to know when she can get up and helps us sleep better. Main issue we have is it would be great if only the bluetooth connection was better. It disconnects from our phones often - after my initial comment here, seller has reached out to me and explained that they have designed it to not stay connected to bluetooth to preserve battery life which helps us understand and accept this limitation. Bluetooth reach could also be better: we basically have to be outside our daughter’s bedroom to make any changes when she’s asleep. Every time bluetooth disconnects there's a lag for the schedule to load which takes a few seconds. Other down side is you can’t temporarily disactivate an element in the schedule, you have to change the days or delete it and redo the whole schedule event if you want to skip it - maker told me this option was under development. We also have very occasionnal issue of light not turning the scheduled color in the morning which is problematic for our child but I just made changes to the schedule which I hope will resolve this issue.
