I have not used a glass blending jar in years, but it is a little heavy, so will take a little getting used to. Though, I may find myself using the single serve jar more. The single serve jar is such an easy, great little plus. Easy to use, a little loud, but not that bad. Wish it had a countdown timer or a timer to set how long to blend for. Overall, great blender. Really like the cord storage option it has. [This review was collected as part of a promotion.]
