I am a pretty recent user of the Syncfusion Essential Studio Enterprise Edition but I feel already the need to spread my pleasant experiences with regards to the products and the excellent support services of this company! Being mostly a winforms developer, I come to say that the Syncfusion Essential Studio Enterprise Edition has practically one control for every possible need! Their controls are very straight-forward to use and well documented. Moreover, the accompanying examples are very illustrative and even provide ideas for usage in your own application(s). Their support is AAA class! Their response time is very short and straight to the point. Even if you ask for something that is not currently supported, they take your request in serious consideration for their future releases. They really care for the customer service and I think they excel in this field!
