Bougt the Amazon Echo Dot (2nd Generation) the moment it got released on 20th October 2016. It is a pretty much must buy item if you are a tech geek as it only costs US$49.99 (S$71).
I have two Amazon Echo at home. One in the Living Room and one in the Master Bed Room. I used it to controlled my water heater, lights, television and playing radio on it via TuneIn. It makes me even a lazier person. I used to switched on or off my lights manually, but now I have Alexa (Virtual Assistant of Amazon Echo) to do it for me.
