I have only shopped once at Everbuying but my experience was only positive, so I would definitively order there again. I ordered two Rock Zircon RAU0501 earphones there.
What I liked about Everbuying:
+ Lowest price for my item I could find
+ Surprisingly fast (9 business days) and free shipment
+ PayPal Payment possible
+ Reward system (EB Points) for even more saving
+ Support: quick responses to my questions (within 1day)
The only improvement I would like to see is the missing HTTPS protocol for the "Your Account" side, so at the momemt I would rather not submit my credit card information at Everbuying, but use PayPal for payment instead.
