This mug is great for the office. I love that it heats up the water so you don't have to boil some yourself. If you don't have a watercooler at work it's definitely needed.  It was simple to set up and use. My only issue is that I wish the mug held more ounces. It's a standard size but I love to make giant cups of tea. I love that your drink stays hot all day. Sometimes you make your tea and coffee as soon as you get to work and get so busy that you only geta few sips. You now don't have to go and microwave it so it gets hot again.
