I was impressed that there was no lagging when photo editing it.  I switched from PC to Apple which might take some adjustment.  If you’re like me,  I recommend that you watch some YouTube videos on some handy tips.The only thing that irritated me was that the package was left on the doorstep for hours.  Nobody signed for it.  I shuddered to think what might happened if it got stolen. Definitely worth investing Nest or Ring door bell even if nothing got stolen.
