The selection of controls that are part of this WPF studio is really amazing and of great importance - more than 100. The documentation is easy to follow, so getting aquainted with a new control is relatively straightforward. If one needs help or have additional questions the Support is very good indeed - fast and very usefull. I am also fond of the App - that allows me to track the status of incidents on my HTC One (a bit of commercial for The Phone!). I have been using it for a couple of month and can only say - this is the set of controls for WPF that you need. The product is very nice to work with, and the samples together with the excellent documentation makes it a must have for any serious WPF developer!
