I love my echo dot. I have four of them and they really help make my life easier. They can control almost everything, lights, locks TV, music, thermostat. It hears you almost all of the time and I've run into very few issues with it overall. I really couldn't ask for a more helpful device. It's even more handy when I found that I could get a battery base for it. The GGMM D3 base that I found lets me carry the alexa dot around pretty much anywhere. I love that I can take it into the bathroom with me and listen to music while I shower or take it outside and listen to music. That's really the only thing I think it was missing.
