I tried these guys today.
Needed a config and it all seemed to go fast, after 10 minutes i had my config but it didn't work.
When I asked which proxies they used they couldn't tell.
Then I was told it needed anticaptcha service.
Which makes the config much more expensive to run, if they would've told me this at the beginning i wouldn't have told to continue building the config.
But I never got this info, which normally any config maker would warn about it, it's pretty standard.
So i paid 50$ for 5-10 minutes work, for a broken product, I asked for refund or partial refund, i understand they have invested time, but this request has been completely ignored.
Be careful with these guys, ask enough questions, they don't care about you as a customer.
