[EX Q]: We give this product high marks for ease of set-up and are satisfied thus far with the speed of the processor, which was an area of slight concern when we purchased. Recommended for word processing, Internet browsing, etc
[EX A]: positive

[EX Q]: Simplest, yet sophisticated smart plug. I was looking such outdoor smart plugs so that I do not have to go all around the house to turn on and off the decorative lights for festival time. These were just the right stuff. It worked just fine, 1) Easy installation - The app is self explanatory on how to install 2) Quick and fast connection 3) I have plugs all around the home and have no issues in connecting them.
[EX A]: positive

[EX Q]: I really wanted this to work but when compared to other medical grade devices, the Pulse and the O2 readings were way off. It was so useless that I returned it
[EX A]:
negative
