I have been using this service for over a year. The proxies are of high quality, and importantly, there is a wide selection of subnets. They show good results in operation, and the speed matches what is stated on the website. There are often promotions, and I buy a lot of proxies, which makes the purchase advantageous. The prices are reasonable. Whenever I had questions, the support always responded quickly, and proxies can be replaced within two days without any issues.
