On a whole this remote is fantastic and I've found it so reliable! even when the app isn't quite working, the remote is normally floorless! At first I thought it was a bit of a strange concept but after using it for about 6 months I completely get it! its excellent! The only problem I've recently discovered is that it does not fit some brands AA batteries. I use EBL rechargeable batteries and also tried Bonai AA aswell and neither fit, but Duracells do. My theory is that the AA storage bit was designed around a Duracell and they provided 0 wiggle room for any other AA batteries. both the EBL and Bonai have fit all other AA battery slots I've used them in just not this one which is a little annoying when I run on a rechargeable EBL set up but it's only a small inconvenience and other then this I have 0 problems with the device and I imagine 90% of users will use Duracells anyway. Overall 9/10 really happy with it just keep the batteries thing in mind
