I like how easy it was to set up an account, add products for sale & get paid quickly! The customer support team has been great as well - they are super quick at responding (even when you're in another time zone).
There's not much we dislike about this program so far. We've had success with our first few sales using their services but have yet to make any money from them ourselves. If you want your product sold online internationally then use ShopLo!! They will help take care of all aspects including shipping/delivery logistics / payment processing etc.
