What do you like best?
Online payment backed by a large bank (Capital One) that lends a certain level of protection. Provides for mobile credit card processing. It has specialized apps for both IOS (but will not work with jailbroken phone) and Android (however this one seems flaky). Attractive website and well protected. Reasonable rates compared to other options out there (not really better, but in line with others).
What do you dislike?
Very little to set it above or separate from the myriad of other online payment options. Has fairly strict requirements for you to be an accepted business. As such, some types of freelancers, cottage industries, etc might be forced to look elsewhere. New business needs to wait for approval - sometimes taking a while even after accounts are set up.
Recommendations to others considering the product
I would not recommend over other options unless there is a special reason for you (such as your business accounts are with Capital One). It functions well enough but nothing sets it above and beyond others while having some compatibility issues (mostly Android based mobile).
What business problems are you solving with the product? What benefits have you realized?
The ability to process credit and bank cards online.
Allows for mobile processing of payments.
Online retrial of payments & invoices / receipts.
