i bought it for 2 reasons:

1. static sites are lightning fast -- of course, it doesn't have PHP, so no processing is needed. all the necessary components needed to display your website is ready to use. it's like... static site = ready made cake (you buy at the store), while accessing your wordpress site = baking the cake starting from powder in your home.

2. security -- because all of your wordpress backend is hidden somewhere else. gone are the days where you worry about cyber attack. bye-bye hackers trying to take over my site.

honestly, i had problems running it from localwp. But no problem at all if my wordpress site is hosted in a hosting company. So, that's all good. This is a much needed plugin for whoever own a wordpress site.
