Compact enough works well in my office. There's an ounce tab/measuring device for the water level on top where you put water in. If you put more water in than the measuring tab, the water will leak all over the place. I find it easier to just put water in my cup and dump the cup of water in for a precise no drip brew. 
It seems to be well constructed as it weighs heavier than it looks, I expect this to last a long time.
