A great option for the price. You regularly pay $3 for 1 gigabyte of traffic and get a full package: - A huge number (150 countries and 7 million IPs) - Various types (residential, mobile, corporate), HTTP and SOCKS5 protocols - Convenient speed (averaging around 10 Mbps), latency around 0.5-0.6 seconds - Rotation every 15 minutes - Ability to export lists in TXT/JSON - Availability of API Sometimes there were issues, but the support team always helped (having Russian-speaking support is a separate plus). There were no promotions or discounts on the proxies, the only time I received a promo code was with my first purchase. But this is not critical, as the price is already very affordable.
