BIO CHEF LIVING FOOD VACUUM BLENDER. Blender jumps on the base at the moment when it starts work on H speed. The vacuum accessory on the top also moves and I have to hold it because it fell once. Also, the vacuum does not work after finishing blending, I have put air back to the blender with the small piece of gum on the top, under the vacuum. The motor is very loud when on high speed and even on H speed when the frozen fruits are on the top it does not take the frozen stuff down, I have to stop it, move the blender up and down otherwise it will blend only the stuff in the bottom..... wasted money
