Useful only if you pay

Interesting plugin, but since it’s not responsive it’s basically a broken product … unless you pay for it.

I can understand the DEVs want to make money, which is fair, but offering a plugin that isn’t responsive in 2016 is sadly rendering it absolutely useless.

Every half-serious website these days is (and has to be) responsive, so better use one of the other free plugins that have that feature built in already.
