Highly Recommend
I compared it with Telerik and some other products. I made a Prototype with each of the Libraries I could get. I think in direct comparison you surely will see the high quality of this controls. They also have a rich portfolio of JScript/HTML (Modern Architecture Angular etc.) Controls, ETL and Reporting Controls.

I've already worked with the Telerik components, and I can say with confidence, Syncfusion is not far behind, and with this licensing scheme, there are many steps forward.
Neilson D,
Desenvolvedor .NET, Small-Business
Faster than other commercial tools.
