I bought 1 ETH worth of ZRX tokens this morning. I experienced some glitches during the process such as getting kicked out just after I entered the amount. The website kept giving me the message that an unexpected error occurred and that I should try refreshing my browser. Eventually, I was able to see my order beneath the ghost of the error message and I was able to complete the purchase. But, it worked and I'm happy. I have my 5,906.975 tokens.
