The best part is its simplicity as it does all things at one place so no need go here or there just do everything with this tool! I think their support team also very good they are always ready 24/7 if any issues arises even after purchase then nothing else but complain them about refunding amount otherwise we have paypal option which allows us 100% money back guarantee!! No dislike thing i found till now only suggestion will be add payment gateway integration like Payoneer etc because currently people should fill email id when paying through credit card hence not much benefit available unless u r using PayPal account.
So please integrate some other way where customers could easily subscribe without filling up details again &again.
