First, thanks for the feedback. Hopefully, I can clarify some things.
The examples we have are in 3 versions: declarative ASP.NET (with C# code if necessary), plain C# (code behind) and plain VB.NET (code behind). With these 3 versions of each example, it should be trivial to understand the code. We are not perfect, so some things might be complex for others to understand, so please let us know which example is not clear and we'll try to modify it to make it easier.
We do not remove anything negative from the forums. It is as clear as it can be. We actually want people to see how we handle sensitive issues -- we have nothing to hide and try to be as transparent as possible. We are never rude and always go out of our way to help.
Yes, we are in different time zones, but more importantly, we don't have the capacity to reply to every technical issue within seconds. In a perfect world, we would have a dedicated support rep for every customer. Unfortunately, technical issues take time to figure out and there are hundreds of other customers with hundreds unique scenarios. We try to help everyone within 12 hours. Sometimes it may take up to 48. If you don't get a reply, drop us a note again or give us a call. We also have to fight spam and the filters do make mistakes sometimes.
As far as a reference to look at the examples, yes, we strongly believe that the best way to learn is by example. That is why we have hundreds of them. If we feel that an example will help you get on the right track, we send you a link to that example and tell you where to find it in the suite. Please spend a few minutes to understand how it works.
Testimonials are copied directly from e-mails. We don't alter them at all. Sometimes it feels good to be appreciated for the hard work you put in. We look at this page once in a while to check that our work is actually helping someone.
I have used them and have mixed feelings. The controls look nice and have a lot of potential. There is a learning curve and many tools work fine. However, all examples are in C# - if you are doing ASP.NET and VB you will be at a serious disadvantage unless you are familiar with C#. And some controls don't work as advertised and you must use work-arounds they post as needed. Searching the forum is useless unless you know the exact spelling and case of what you are looking for and anything negative seems to be removed. I had display issues (their controls covering menus and other controls). And contrary to the constant praising by their testimonials their support is not that responsive or great. Perhaps they are in a different time zone on the other side of the earth, but it sometimes took a day to get a response, and then it was just a reference to look at their examples. The initial cost is low but you will pay for it in time lost during development.
