I didn't hear bad words about it, but it's rather new and expensive so I don't expect too many to have used it. Somehow people don't seem to be eager to share their experience on this service; maybe they are ashamed that they have to use credit card to help Bitcoin transaction get confirmed.
Instead, ViaBTC is reliable, but more and more crowded. Btw, OP tx got confirmed, yay!
I tested it recently, and it appears you can only pay it using alipay at present. I'm almost sure I read it was possible to pay with credit or debit cards when the service first started. It used to accept stripe, but says that method of payment is down for maintenance.
When I tested that accelerator it only gave alipay as a method of payment. I think it also used to accept debit and credit cards.
It says it accepts stripe, but that payment method for Westerners is down for maintenance.
