To begin with, NO OTHER ADBLOCKERS REQUIRE REGISTRATION OR PAYMENT (apart from adblocking as a feature of your antivirus app).
Almost all reviews from people who know what they are talking about are NEGATIVE.
It isn't a genuine app. It is simply a link to your browser.
I tested it with my regular adblocker (AdblockPlus, free) switched off.
All it did was make my browser pop-up, and no real difference at all.
I switched my regular (100% free. Officially on Google play, simple to install) asblocker back on then tested it again. And this proved it wasn't an app, but a browser link, as my REAL adblocker blocked it instantly! This could not happen if it was an actual app. Why? Because my AdblockPlus (free. And genuine) ONLY blocks ads or dodgy sites from MY BROWSER (firefox).
It is obvious many peiple who are seduced by it have little knowledge of adblockers as they seem to all have difficulties downloading it, almost all have issues with dodgy and constantly varying payment amounts. All seem to have difficulties contacting the devs, or getting refunds.
Many get ignored. Nor do they seem to be aware it is the ONLY ONE that asks for payment AT ALL!
If you want a REAL adblocker, go to your browsers offical addon/extension/plugin store or Google Play Store, and get one from there.
You will also notice while you do that, that they are ALL FREE, and none require registration. And are honest in hat they really are browser extensions, not apps.
The fact it needs installed on your actual phone, and not as an extension to your Firefox or Opera, or Chrome, should be a distinct warning.
The warning I got from AdblockPlus told me it was blocking TotalAdblock due to a Web address extension called "[insert website name]*document".
Why would 100% free anti malware or adblockers do thos? And ONLY to this "app"?
Yep, you guessed it, they all know this bunch are really dodgy.
Also, I notice from a good few of the review websites, that many people who didn't even want the paid version had TotalAdblock attempt to take payment from them anyhow!
