Backconnect proxies are definitely not a silver bullet. They can be useful, especially for quick rotation without managing a bunch of separate proxies, but they come with their own set of headaches. Flakiness is pretty common if you're not careful with the provider. The stability really depends on the quality of the backconnect service and their infrastructure. I've seen some work well, but most are just a pain in the ass when they start dropping connections or slow down. Plus, a lot of the hype comes from sellers overpromising, which always makes me cautious. Most of the time, if you're serious about scraping or automation, investing in dedicated proxies or building your own PBNs might save you headaches and be more reliable long-term. Just remember, correlation isn't causation, a shiny proxy setup doesn't always mean better results.
