To check whether a site is legit usually, I do follow a simple checklist to see how well they do.
1) Use WhoisXY.com to check the whois information and check whether the contact information matches with the one in the website.
2) In the domain contact details, is there a valid email address.
3) Is there a valid phone number visible, and does it work ?
4) Go through review about them using Webutation.net and check whether they are scam free.
I checked in for the site that you have specified and was not able to get a clear whois information...however they do not have any suspicious complaint and are considered to be safe.
