Hi Gonz,
This site is relatively new, they have been online for less than five months. There are no informative reviews about them yet.
They seem legit but I have no guarantee on their reliability as a supplier since I have not used them personally. They do accept safe payment methods.
Just keep in mind that this is a Chinese supplier so don't buy any products that are offered as branded. The likelihood of getting copies will be quite high.
Hope this helps. :)
