I like that it's easy to use, simple UI makes for quick set up without any fuss or errors when compared with other services which require more workarounds/tweaks in order get things working properly at first try! The only thing i dislike about this particular service so far would be lack (or maybe just not enough) support options available from them regarding issues such as slow page loading times etc., however there are ways around some problems if you're willing do invest time into learning how they all operate by yourself - but again since its free what else will one expect?!? If your looking solely out off features then don't hesitate because everything seems great right now!! Take advantage while prices last.
Easy website monitoring using statuses; also very customizable via templates / CSS stylesheets provided through their platform itself :).
