Syncfusion

This week I have been working with Syncfusion, JavaScript.
Syncfusion was mentioned at the Dyalog Conference 2013.

My first impressions of Syncfusion is that they have better looking objects than JQuery, however it does not work well sometimes. It’s quite buggy and therefore not suitable for our needs, whereas JQuery is not as buggy. JQuery it’s quite easy to understand and use.
For example, the other day I was doing  a Drop Down List containing checkboxes with Syncfusion and sometimes you could select the items sometimes you couldn’t. At the end I ended up using a JQuery dropdown list .

Has anyone worked or is thinking of working with Syncfusion and/or JQuery? If so do you have any opinions regarding this or what are you building?

Thanks,
