Comments and Reviews
I've not purchased it, but it looks like something a medium company would build in-house. The farsightedness and color filters look very much like the one used in Firefox, and the inline css editor, responsive design and content editor is also included in Firefox.
Furthermore, live reload has been possible for a bunch of years using Browsersync,
webpack-dev-serveror a combination of the two.All in all, nothing that can't be accomplished using Firefox Developer Edition and a properly configured dev environment and certainly not worthy of the high monthly fee they're requesting for it.
