Any experience with Press Advantage or Brand Push?

Looking for some factual information about Press Advantage or Brand Push. I recently started using Press Advantage because I was falling behind on backlinks, and it was a pain in the ass to get them one by one. I noticed some of my main competitors were using similar services, so I thought I'd give it a try.

I start it last week, so I've yet to really see any results. As for all the links, they seem legit. No spam warnings from Ahrefs or Moz, and the DA is pretty good, even with the lowest budget package from Press Advantage.

Was wondering if anyone can vouch for the quality of dofollow links, the online site brands, and whether or not the "big" links expire or are permanent etc.?
