You have to pay to really get any use out of this also, the pay to get features gets in the way for basic use.

I've had this extension installed for several months now. Today, I saw a charge on my credit card from TubeBuddy.com for $43.20. Since I don't have an account with TubeBuddy and I've never purchased anything from them (and the fact that they don't even have a subscription for $43.20), I'm guessing this is fraud. I contacted my credit card company and uninstalled this immediately.

Mostly everything is in the paid version. Plugin efficiency is really bad, killing CPU sometimes.
