I like how easy it is to use as well that you have all of your contacts in one place which makes things easier when searching through them or adding new ones into my account! It's not super customizable but there are tons of add-ons available so if this isn't what exactly fits with their needs they're able t change pretty easily (and often). If anyone has been using any other type software from another provider i would recommend looking at those before thinking about switching over because sometimes its just very helpful having everything under 1 roof instead creating multiple accounts/profiles etc..
