We have the Dot from Amazon ($49.99)..Alexa is the greatest..The only problem you need alot of other products and I think smart phone for light fixtures and phone calls..I;ve seen most of those items lots of times, especially the jar opener...but I like the wrist band and the seniors phone.....
which reminds me I think this year I might give or suggest a gift of ''Google Home'' for a Blind friend...it's going to be so useful for him...endless possibilities, like asking what the forecast is going to do, get it to read to him, play quizzes, play brain games, ask for the times of trains and buses..get it to call a cab... .. .. as well as 'company to talk to''
