As a tech engineer working with data-intensive tasks, I've been impressed with Astro’s geo-targeted proxies. Rotating proxies' free trial was a pleasant surprise. The experience has been smooth and reliable as well, especially with their pay-as-you-go structure — no need for monthly subscriptions. Only $4 per GB with IP whitelisting. It’s refreshing to find a provider that charges based on either inbound or outbound traffic (whichever is larger), a rare show of fairness in today’s market! Integrating Astro proxies with antidetect and headless browsers was straightforward. I was able to export proxies through a data text file, adjust a few settings, and get everything running efficiently. Bulk purchases for buying residential and mobile proxy pools went off without a hitch, and I could precisely target by city and isp's levels. Every proxy supports both SOCKS and HTTPS, which adds flexibility to our workflows. Hope my review on Astro service wil be useful.
