I like that they have many different ways of giving money online as well as through PayPal/Venmo. They also do not charge transaction fees! This is important because it makes it much easier for me to give donations without worrying about paying extra fees. It would be nice if there was more transparency with how my donation is being used.
For example, I'd love to know exactly where each dollar went. But, this could just be a personal preference. We use them primarily for our school's fundraiser
