I've done a kentico site for a customer where I integrated an EPOS system into a kentico ecommerce site.

Pros:

• chm's for API&database
• documentation for some webparts (module equivalents)
• excellent backend for administration
• use of webparts making code reuse pretty easy (change inherits and you're there). There are no manifests so webparts are just deployed to a folder . This means you'll use a lot of FTP, as you can't upload a component and have it install.
• some useful built in components

Cons

• lack of community -their forums are very small, with little in the way of programming questions and answers
• few 3rd party components
• it costs money - $1000/site (and that has no source code, no webfarm support,no staging and only 10 products for ecommerce site meaning the $1500/site version is required)
• poor development environment - localhost version has 30 day timeout, ecommerce version limited to 10 products etc.
• odd object model - you need to create document types, documents,document templates and assign to a menuid etc.
• requires full trust for some configurations so will not work on all hosting providers and is inherently less secure than a medium trust site (such as dotnetnuke)

In general I've found it much tougher to work with than dotnetnuke, particularly as you have little support. The backend is very good for site administrators to use, so if you're not doing a lot of development I think it's a reasonable choice (though my preference would still be for dotnetnuke or sharepoint depending on clients needs)

Hi Cathal,

Thank you for all the Pros mentioned and let me shortly comment the Cons:

Cons

• lack of community -their forums are very small, with little in the way of programming questions and answers
  
  The solution is well supported by the support team. +There aren't unanswered questions at the Forums.
• few 3rd party components

             That's right only if 200+ web parts won't cover your needs. +You can anytime easily add your own Webparts. +Open API.

• it costs money - $1000/site (and that has no source code, no webfarm support,no staging and only 10 products for ecommerce site meaning the $1500/site version is required)
  
  Right, fully supported complex CMS has this price.
• poor development environment - localhost version has 30 day timeout, ecommerce version limited to 10 products etc.
  
  If you buy any license you are eligible to get unlimited number of licenses for Testing/Staging/Developing purposes - without any timeout. Otherwise you can ask the support for  extending the trial period  or you can use the Free edition for free.
• odd object model - you need to create document types, documents,document templates and assign to a menuid etc.
  
  This object model is coming from client’s needs - to have fully customizable document types, document templates for better cloning and managing the pages... etc.
• requires full trust for some configurations so will not work on all hosting providers and is inherently less secure than a medium trust site (such as dotnetnuke)
  
  The list of supported Hosting provider is pretty long. +Kentico works also under Medium Trust environment.
