If this wasn't Tassimo branded, it would probably sell for about $6-7 at Target. The quality is OK but it's not high end. If you don't screw the lid on VERY tight, it leaks between the lid and the mug. The way the flip-up tab opens to reveal the drinking spout isn't as convenient as it could be. When fully open, the tab still gets in the way. You have to tilt your head back a little further than normal, and it works fine; you can't simply tilt the mug further, as the tab is bumping your face.
Finally it doesn't keep coffee hot as long as a premium travel mug with vacuum seal I purchased. Of course that one cost $30, but it never drips, never spills, and keeps coffee hot for hours.
Summary: For the money, this mug is OK - hence my average rating.
