Quick and competent and more importantly, reliable.
I purchased two items through their service, once as a guest and another after registering. Delivery of both purchases was prompt and the explanation of activation, given that it was through Steam, was accurate and helpful. The payment methods they provide are Paypal and Paysafecard, and having used Paypal the transaction went through smoothly. I received both items within minutes of purchase, and email notification of confirmation of the payment and then summarily of the product being ready to be activated. However, I ended up making a mistake in thinking one product was another, and they solved the issue with more than haste. Providing a discount code for another product and sorting the whole issue out. The customer service was prompt and wasn't hard to deal with at all. The email exchanges were prompt enough and coherently written, and polite. More importantly, they were helpful with the issue and resolved it in a more than satisfactory manner. It's a good service, one I'll be using again in the future.
