We had this professionally installed during a full bathroom renovation, so I cannot speak to the ease/difficulty of installation. I can say that this little mirror is quite mighty - and such a game changer for getting ready for work in the morning. I am far sighted, so I need reading glasses to see up close - that's pretty hard to manage when you're trying to apply eye makeup. The magnified, illuminated mirror has remedied that problem and it is so easy to use and clean. Love this mirror!
