My experience with Syncfusion Essential Studio ASP.NET MVC was awesome. The best features i experienced from this product was the essential grid and tools which helped me to deliver a quality web portal project on time. I didn't experience any bug with the use of the controls and syncfusion has a superb support via their samples, onlinehelp and knowledge base. This will get a developer up and running with their product suite. I hope to explore syncfusion Mobile MVC, WinRT (XAML) and Windows Phone controls soon. Thank you.
