Bests & Worsts Reviews from Amazon

Sold as having "7-days activity alert video storage in YI cloud free of charge" Nope. You get a one month trial, then they start charging you. Sold as PTZ (Pan/Tilt/Zoom). Nope. The zoom is just "digital" zoom. In other words, no zoom at all, just a way of making a part of the picture larger with a corresponding decrease in resolution. You can do that just by playing the video on a larger screen.
