These are some of the cheapest proxies for social networks. You can purchase a proxy for just 5 days, which costs very little. There is no trial period, but within a day, if something doesn't work out, you can get your money back. I haven't had such situations, but at the beginning, out of the five proxies I bought, one turned out to be non-functional. I contacted technical support, and they replaced that proxy. Since then, I haven't had any similar problems.
