Their Xamarin UI tools are great Their Xamarin UI tools are great, and the free Community license is indispensable for small developers like myself. I've contacted their support group a few times, either with questions or bugs, and their responses are timely and helpful.

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.

Excellent Support From other reviews, they seem hit-and-miss, but my experience is excellent. One query I had on the forums was down to the way I was using a control, and another query is a genuine bug report. They got back to me within 24h and are letting me know the bugfix progress. I can't ask for more - especially as I'm only on the community licence.

Powerful and complete features I have to say that Syncfusion is a product that has exceeded my expectations when using it in WPF. When my client requested that my WPF application must have a PDF viewer with annotation and clickable hyperlinks within the PDF, I was at a loss for how to fulfill this requirement. However, just when I was feeling overwhelmed, I discovered Syncfusion, which proved to be the perfect solution to meet my needs. It couldn't have come at a better time.

A great product - Components are plenty, and easy to use (we use Angular components, but the others seem to be the same). - Documentation is good. A lot of examples, how-to, and API docs. - Very supportive, the support team replies support tickets that solve our issue quickly, detailed.
