It works and there are no real issues with it. The data cap on free users is very low at 2gb, i went through that in about an hour or two. They do not let you signup your email if its considered (by them) to be a disposable email, i used a mail.com email and it was rejected. this pretty much annoyed me because it is by no means a "disposable email". While it functioned it is pretty much useless as a free application.

The VPN is pretty nice for my needs, but having the whitelist adfiltering on even when the VPN's off can be pretty annoying. You have to either disable the extension outright (or, at least, disable the extension's adblock) or whitelist the site (or, at least, their advertising) if you trust the site and want to allow their ad on your face. (I'm usually relatively chill with ads so long as they're not intrusive.)
