It’s a great plugin

I only use it for monitoring my traffick statistics and it works great; it even has a mobile app that lets me monitor several sites from one place on the go. I know that JetPack is much more that traffick metrics, but for many of the other services they offer I use other plugins… thankfully, JetPack allows me to turn off all the features I won’t use, so that my websites don’t get bloated with excess code from them.
