The service is very inconvenient to use. They do not provide the option to download proxies in bulk, and the ones you collect manually through the dashboard die after a couple of hours. Although they claim that proxies last 24 hours, I only took from the first page.
Even though I contacted support, they couldn't help me configure their service for my software, so I ended up buying proxies and adding them manually. Then I wrote a script after consulting about the limits. It turned out to be no more than 1 proxy every 2 minutes or 30 per hour. I was taking 1 proxy every 3 minutes, but after a couple of days, I got banned. If you use software like ZennoPoster or XRumer, stay away from this site. They ban accounts without refunding money. For such a service, it ends up being very expensive!
