It is very easy to use with great apps for every device (phone/tablet), it has an endless amount or features that make sense in everyday life - like having my keys under one dashboard! I didn't find anything bad about this system so far; everything seems perfect at first sight but i know there are some bugs here & then they will fix them fastly as always from their customer service team :) They do not only work online via webbrowser anymore since version 9-10 now we have our own appstore where all updates come directly without internet connection which makes me more comfortable when using something important ;-).
