The ability of being able to track multiple printers in one account has been very helpful when I have several people using them as well! There isn't much that we dislike so far but there are some features such as "Find My Printer" which may be easier said than done depending upon your network setup/configuration (although this was not an issue).
It's easy enough if anyone else can use our computers however having access via mobile devices would make things even better. We're trying out different services throughout each month; usually because they offer something unique like integration into Salesforce etc., though sometimes just due to price differences - especially during holidays where prices drop significantly!
