The ease to implement it with minimal efforts is one thing I like about this product as compared to other products available out there. It has good performance which makes its usage very easy even when you are working on low end devices or mobile phones. There isn't anything specific that I dislike from here but if your application requires something more then go ahead otherwise everything seems fine at first sight. If we talk about price factor what can be said? Its not much expensive than others so no complains over pricing too. We use OrbExpress SDKs to build our own services based software's using C++/C# languages along side Visual Studio 2013 IDE environment.
