I like how easy it is for my clients to use our payment gateway service compared with other services out there. We also have an API available so we are able to integrate into existing systems as well if needed. The customer support team has been very helpful over email when necessary and quick responses otherwise! There really isn't anything i dislike about this product at all but they could improve upon adding more countries outside North America into some type of master list where you choose what country your client would be using instead of having them select one option only. Paying invoices quickly and easily without any hassle. Its fast, easy to use payment gateway for bitcoin which is very secure as well. Nothing much except its quickness it doesnt have too many functions like other gateways do but not really an issue at all so far great! I would recommend this if you are looking into fast reliable ways of accepting bitcoins with out having issues afterwards such as chargebacks etc because most credit card companies wont allow your business unless they see there own risk involved.
