Ccleaner is a great product backed by the lousiest customer support system that I have ever encountered... The chatbot is totally worthless... And chatting with a real live breathing keystroking human is unthinkable... Even their support request form is screwed up... It noted that my plain old gmail email address format was invalid (what could possibly be wrong with @gmail.com?)... My issue was/is a 1 year too early auto renewal... They wanted to charge me to renew in 2/26 but my subscription is good till 2/27... Still have not heard back from them.. May have to sort it out on the backside with amex
Recommendation: Buy CCleaner Pro ... and pray that you never need to contact them for an issue
