Been working with Octo browser for over a year. There were over 1000 profiles at peak. In comparison with others I have not found another option at a lower price and the same quality. Octo browser perfectly copes with its tasks. The support is responsive and in some points I respected them as much as possible.
What's great
responsive support (13)multi-account management (15)
I've been using the browser for about 2 years, so I'm constantly watching it improve. I especially like the speed and the ability to use it anonymously.
