It is excellent and very little battary drain. I have had it since my HTC Hero days.
1) You can get it for freeHow/why is this a "must have"? If it is to find your phone, it seems worthless to me. I seldom have GPS or Background Data checked. Won't be accurate without GPS, won't work at all without background data. Very easy to back up to SD or a PC directly without an app. I guess the antivirus part could be useful. I just don't like apps that take up space that I don't use and do drain the battery (even if a small amount).
