I personally am not a fan of their translator. The server is often slow (many online translators are). Instead, I prefer
ConveyThis.com - Free Website Translation Toolbar and Button. It doesn't suffer from slow down because it basically combines all online translators into one tool. Also, it tracks translation statistics for your website so you can see which languages your pages are translated the most. All of this is combined into one small button. I really like it a lot.
