Excellent experience with Syncfusion!

Syncfusion is a product that makes life easier! I use it to create Blazor applications (server side and webassembly) and the controls speed up development a lot. Furthermore, if needed, it is possible to ask for direct support that is never long in coming!

It is the most complete component set available. Also very handy is the fact that there is a community edition, this gives me the opportunity to test thing at home without buying a separate license.
