I chose Syncfusion suite because of it's extensive functionality on WPF grid controls that meet most of my expectations. After I started using it, I'm very impressed by its functionality, and more importantly their support team who offers very helpful support while I'm learning on utilising grid controls for my various needs. Whenever I raise a support call, Syncfusion support team always come back useful information, and quite often supplies with sample code on how to achieve what I want. Highly recommended.

We purchased Syncfusion Essential Studio a few years ago and pretty satisfied with this decision. Our application includes all kinds of win forms controls and syncfusion controls fit our needs. However sometimes we get stuck with using syncfusion controls in some specific way or we find a bug with them. And Syncfusion technical support really helps here. They do their best - response quickly and accurate. I like their Incident/Ticket system. For now I created about 10 issues and all were successfully resolved. You never get lost - they help and even you have found a bug, it will be fixed in the nearest release, which are deployed about every month.
