It was simple to use, I had no problems with it at all! Very quick transaction time as well which made me happy when making my first purchase using their platform (Bitcoin). They have great support team who were very helpful in answering any questions or doubts i may've been facing during this period of transition between platforms/transactions etc... Nothing actually really bad about them but maybe they could make some improvements by adding even better security features like 2FA authentication for example? Great experience overall while trying out new exchanges - nothing much comes up against SWAP either good nor not too many downsides compared other services we tried before switching over here :).
