I never heard of that site until now. I tried searching for a review of that site in google but I can't find any. They are not even running a HTTPS for a site so I wouldn't risk using it. If you want to trade btc to paypal just use those legit sites and well known like paxful lbc and here in forum.
I too can't find any reviews on this site, but you can see many comments on their site. I don't waste my money and time in using such sites.
In this forum, if you're a trusted member then you can do small trades with PayPal otherwise, you can't do any trades using PayPal. Other sites also charge a quite high fee for using Paypal funds to buy bitcoins.
