Progress Kendo UI includes over 110 cross-browser JavaScript UI components that closely mimic their desktop counterparts. For me, they fill the gap where Visual Studio either has nothing or forces you into using a server-side control. I've been using it on nearly a daily basis for close to 10 years. Implementation and integration are relatively painless, and I've yet to find any components with no documentation. I've never really had to use customer support because the documentation is straightforward, and anything I'm unsure about can usually be answered in the forums.

Sometimes the sheer number of components and how they're categorized can make it challenging to know about all of them and/or to locate the appropriate documentation. Review collected by and hosted on G2.com.
