I love my Designer 725 with the Wildside+ Jar. I just received the new upgraded version of the Wildside+ through the blender rewards program but the first one I received was defective (had a bad vibration from a manufacturing issue), but I recorded a video of the jar vibrating and emailed it to customer service and they immediately sent out another. This one is fine and I'm extremely happy with the upgraded lid. #Blendtec rules.
