They usually work, but think twice about using them. It seems these ad blocks are sometimes effective, but free sports streaming sites, for instance, can now obviously detect your ad blocker, so you don't get past go. The other thing people need to think about is that a lot of free sites we access are free because they have ads - but if everybody has an ad blocker, such free sites are no longer viable and will go out of business eventually. The reply to my comment by AdBlock is appreciated and makes sense. I don't mind ads on free sites as long as they are not too intrusive or try to hi-jack you to somewhere else!

I paid for Adblock Premium I paid for Adblock Premium. However, I regularly (every day or two) find that it reverts to the free version. I have to go through the process of "Upgrading" and then select I have already upgraded, put in my Paypal email address, wait for a new verification code, enter the code and then set all the options I want to use. I contacted Customer Service (ticket 263916) and was told that developers are working on a fix but no estimated fix date. Can I have a refund - no, I can't, apparently. Wasted my money

Paid £9.95 but no reduction in ads so… Paid £9.95 but no reduction in ads so cancelled only to find that they were trying to bill me every month. Arranged a chargeback with my bank and a block on the monthly fee but each and every month they try and take a payment which my bank blocks.

I had to figure out that Adblock VPN… I had to figure out that Adblock VPN does not work with Linux OS. Yet they take your money. When asking for assistance you'll get a bot, or a self-help screen. Customer service is virtually non-existent.

Beware keeps charging after unsubscribing Installed the app was charged 14.99 cancelled the subscription as adblocks instructions for iPhone then noticed was charged again even though I’m unsubscribed according to the app. I had to create an account on the Adblock website and unsubscribe again from there. From the reviews I can see this happens to most people. Unsubscribing the way they tell you to doesn’t stop them charging you.
