[This review was collected as part of a promotion.] I've been using my blender for a year. Yes it does move a lot. It was weird. I got non-slip liner for underneath. The plastic cogs did wear at first but it did not effect the performance. I did tons of research as I was thinking of purchasing a vitamix and in a consumer report YouTube video this blender beat both the vitamix and ninja. I've been using it for a year now. It blends whole carrots, apples no problem. It puréed meat for my senior cat. Still works great. The trick is making sure you have the right fluids. Definitely worth trying. I love this blender. I got mine on sale Happy blending.
