Alexa is looking better than ever! I love having this little screen besides my bed!
Asking her to show me movie trailers, set alarms, and make calles has never been better!
I made a video review on this little guys! Check it out and I hope this helps one of you interested in

This is an excellent smart device with one major flaw that makes it unbearable.
There’s no way to deactivate “Things To Try”, which means you’re forced to watch on-screen
