How can you find out if DHgate.com is a reputable and legit website?

Well look on Trustpilots review site and that is where you will find the best answers for the experience they gave me.
THEY ARE SCAMMERS AND I DO NOT JUST MEAN THE SELLERS BECAUSE DHGATE PROTECT THE ROGUE SELLERS WITH DISPUTE RESOLUTION RESTRAINTS THAT UNBELIEVABLY EXIST IN TODAYS ONLINE SHOPPING.
I made 3 purchases and all ended in dispute and 2 purchases were never sent or indeed going to be the third was goods not as described and cost $170 I have been offered by DHgate $50 which as you can imagine is an insult with the only other option to return the items back to the seller for a full refund (Postage is $120) so not really an option.
BUYERS BEWARE AND SHOP ON EBAY WITH PAY PAL PROTECTION.
