Untested controls I have been using some of their controls for Xamarin Forms for 5+ years now. My honest opinion is that their controls are highly untested. So if you are aiming for a more complex use than the shown in guide, you are going to find out some important bugs. I can say I found problems with almost all of controls I used. Some problems are just easy to solve (elements of style customization being ignored). Some other are just making the whole control unusable. For instance, SfChat has an obligatory behaviour of starting the listView on the first message and automatically scroll till last one. Super cool when you have 20 messages. UNUSABLE in real cases where you have 1500 messages as you would just stay staring at the screen scrolling by inself for 30 seconds without even being able to interact with the control. If you just want the plain control without any type of customization, it definitely saves you some implementation time.

They went the extra 20 miles to support us We were converting from a graphic library that has not been supported for quite a few years to SyncFusion. Our application requires continuous graphing of high volumes of data in a multi-threaded application. SyncFusion support provided tremendous support to get a solution that would support our needs. They were very patient when I was confused and just did what it took to get this working. What they had to do was not trivial but they managed to get it working. I am VERY impressed.

Greate experience with Syncfusion Grid component We are using the Grid UI component which is best in class. It provides many useful features such as filtering, sorting, searching, pagination, etc... You can also customize the menu and other stuff for your own needs. The Syncfusion support is very great. You can submit ticket for any question related to those components. Usually, you will get reply less than 24 hours. They will even provide technical support meeting to help you debug issues. And for the bugs you reported, they always try to fix them in the next release.

I am struggling to use their products… I am struggling to use their products with community licence. Almost every product have problems. Desktop widgeds not properly work at Visual Studio. It messing up all project. Asp controls even basic project not properly setup. Microsoft's standart controls far more nice.

Worth building on A superb set of widgets that works the same in countless frameworks from plain Javascript/Typescript to Angular, React and even Flutter. The company is also very responsive to any bug reports with most issues addressed in 24 hours. Overall, a very solid foundation to build on.
