Why do I say this?
For one, they are a Chinese supplier offering branded electronic products - one of the top things you should always remember when shopping online is that branded products and Chinese suppliers never go together. 9 out of 10 times these suppliers are indeed selling fakes/copies/replicas/imitations.
Second, false advertising. When you visit their site you'll find the PayPal logo along with three international credit card logos (on the right lower panel), giving you a false sense of safety but when you make a test purchase, you see that PayPal/credit cards are not an acceptable form of payment. They only accept Western Union and Bank Transfers - two BIG no-nos.
I think these should be enough to convince you to look elsewhere.
By the way, what products are you interested in? We'd be glad to help you search for more suitable suppliers.
