It's one of a thousand "lance" sites just like it, where Indian high school students fight over the chance to build you the next Facebook for $150. The quality of the work you'll get from one of those sites is terrible. If you're going to consider using it, I'd suggest hiring 3 separate developers in parallel, in the hopes that one of them may actually deliver something usable. If you're a developer, you probably shouldn't waste your time looking for work there, unless you're prepared to compete on price with the $7/hour crowd.
