Any one using Universal SDK from Airpush ?

I’m asking to see if the push notification ads for 3rd party apps is still profitable as it was years ago , I was using Bundle 2 from Airpush but I dropped it after they reduced the rates , and now I need an SDK with push or just Banners and interstitials for my 3rd party app
any suggestion ?

Push notifications are shittty everywhere. Try to focus how to increase your ecpm by looking for better traffic quality.
