Stability is a common issue with proxies, especially if you’re dealing with platforms that actively block them. I’ve learned to avoid public lists and go for providers that offer a United States proxy server server option. These are dedicated, and they tend to keep a more consistent connection. ProxyElite is one example that has worked well for me—they offer a variety of servers, and their trial period gives you a chance to test them without committing upfront. If you need something for e-commerce, focus on proxies labeled as “dedicated” or “static.” They usually hold up better and are less likely to be flagged.
