Pros:

• There's no need for you to wait for the other party to buy or sell their token. Usually what happens in other exchanges are when you try to sell a specific token you will need to wait for a couple of minutes if there's no one willing to buy that or the price isn't that favorable for them. As per the site everything will be in an instant.
• A lot of tokens to choose from. When exchanging you can either have it via USD or ETH

Cons:

• STEEM isn't included in the market yet.

Overall this is a good alternative to other folks who wants to try instant exchange. The site is kinda neat too btw kudos to the website designer.
