I have some difficulties with the proxy

[BillRey]

I need to use an anti-detect browser for tasks related to targeting, and if I have decided on the browser, I will have some difficulties with the proxy. After all, I need a solution that will give me access to many IP addresses. According to the declared service packages, I came across a proxy compass https://proxycompass.com/free-trial/ that is more than suitable for me. What do you think I should pay attention to? Is it worth using it for these tasks in general, and what difficulties can I face in the future?
