Been using it for the past 6 months and my experience is very positive. Its easy to work with and transactions are very fast. They have a good selection of tokens to be claimed in the faucet section, a small number of coins rarely have funds to give though the faucet system.
The transactions into the system are extremely fast for the coins i have experience with and never had any problems. Converting from one coin to another is easy, though there is not conversion for every possible pair, you need to convert to a "main" coin like btc, scc or dash to be able to convert to any other token offered.
Overall though the experience is great.
Awesome site!
