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.

Lots of options, excellent support After years of using SF professionally, I always have been able to get speedy, expert and very friendly support from the SF support team. The number of options of the SF are quite overwhelming at first, but the documentation (e.g. software examples) have been very helpful to get the most out of the package.

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.

No Need to Reinvent the Wheel With Syncfusion’s JavaScript suite, we have a lot of components ready to use; each component offer some events to bind and customize its behaviour. We could use business-ready, updated web and mobile UI components. These days, it’s impossible, time and money-wise, to think about writing complex UI web-mobile plugins yourself. On application side, Syncfusion offers a powerfull suite for manage xls and doc formats, and a great support portal.
