The media could not be loaded.  The Vitamix I received has multiple serious defects despite purchasing it brand new/for medical reasons. Reading through other reviews, there's a pattern of very similar issues that resonate with my experiences:1) Motor/blade would just stop spinning. I’d have to unplug + wait a long while before blending again only for the issue to repeat. Problem has become progressively worse to the point that it often only blends for several seconds at a time before stalling out. This adds up to about several hours to blend a (melted) smoothie…2) The entire blender would start shaking/vibrating to the point it’d spin on my countertops(can easily fall off). Pretty sure the blade is supposed to be the only thing spinning... Gradually increasing the speed(which, you shouldn’t have to do for a quality blender this expensive IMO) hasn’t helped. Now I’m left with a safety hazard that has seriously damaged(left many marks) my counters.3) Malfunctions are often accompanied by awful smells/loud noises. I now use hearing protection whenever I’m using my Vitamix.Really disappointed as my family has used Vitamix for the longest time/never encountered such issues. I've used the tamper every time with this product and am only making simple smoothie blends that are easily/well-tolerated by much cheaper/older/hand-me-down blenders. Would recommend paying close attention for early signs of similar issues if you purchase this . Also, place a protective barrier on the counter to prevent property damage that can be more costly to replace than the blender itself.
