I honestly didn't know what to think when I read that this Black and Decker blender had "quiet technology". I deemed that to just be a selling tool and delighted in the fact that this blender has a GLASS jar instead of plastic! Boy was I wrong to judge. Not only do you get an easy to clean glass jar instead of trying to scrub greasy plastic, but it really is way quieter than any blender I've ever seen! It's like your neighbor is using a blender and not you! 10/10 recommend!
