Popunder script

Anyone has experience with popunder scripts? I was using popunderjs.com, they are working, but CS lagging and they doubled the price again to 3K USD/year which is really steep.

PS. I want a real popunder script.

Try BetterJsPop or AdSpyglass, both solid popunder options without the crazy price tag.

https://github.com/nicxlau/BetterJsPop this was updated 6 years ago. Will not work with recent browsers.

Does adspyglass really offer real popunders? Nowadays it is hard.. hard especially for Chrome. Hence the price from that popunderjs (it is a one man show from some Vietnamese genius, I hate him and love him at the same time)
