Don't be fooled? – Opa! - Call Recorder with Free International Calls Review

They'll offer you a 'free' credit if you write a positive review BEFORE TRYING OUT THE APP. So pretty much all the 5 star reviews are just people wanting a small lousy credit towards their calls. You can't even earn them you have to buy them?
