I like that it's easy to add videos from Youtube or Vimeo without having any technical knowledge of HTML5 video coding! It is also very flexible in terms what you can do with your ads (creating banners for example). Sometimes there are glitches when updating an ad but this isn't really noticeable unless someone clicks through one too many times before they get back into their page where no more errors occur - which means people don’t notice until then anyway :) We've been using klastech since we started our website about 6 months ago now so all aspects have improved over those six month period including ease/speed at adding new content etc..
