I bought this mug to use at my desk at work. I would usually use 3-5 paper cups through the day for water, coffee, smoothies, or cereal.
With this mug, I can do all of that and go green! I have not used it in the microwave as yet. However, I use to it eat cereal, drink coffee or tea, and drink my smoothies. The width is excellent to spoon out the little bits of smoothie that remains in the bottom of the cup. The lid is great, too.
Overall, I have no complaints. It cleans easily and is easily to hold. I'm pleased w/my purchase.
I've only had it for a week, so hopefully this helps.
