Helping a friend with AI training data

Helped a friend collect some vertical-domain training data a while back. Once the volume went up, the old proxy pools started timing out and getting blocked constantly. The retry logic kept getting longer and more complicated — pure headache.
Switched to helodata residential proxies. The pool feels solid, success rate holds around 99%, latency is fine. Standard protocols, just replaced the old ones, almost zero integration cost.
Using it on a pay-as-you-go basis now and it’s been reliable. At least I’m not rewriting retry code every day. Anyone doing data collection or AI-related work can check it out themselves. Got better options? Recommendations welcome.
Just to add, the one I’m currently using is this: [ ] Success rate is a bit more stable than before, for reference
