I used them twice so far, it's an automatic bot, you have to buy bitshares (you can use steem, btc anything really.) on Openledger then with the Bts, buy Whaleshares on the market, then follow the instructions here, http://whaleshares.net

its not 100% cost effective like @randowhale but I used it on a posts and got many more views therefore votes.
