VEVOR Milkshake Machine, 375W Milkshake Maker Mixer, Single Head Drink Mixer Blender Machine, 3-Speed Milkshake Blender with 820ml Stainless Steel Cup for Commercial

The electronic motor speed does not decrease when stirring liquids. The mechanical motor speed will change. Therefore, electronically mixed drinks will be better.

You can also use other cups. But if the size difference is too large, it cannot be placed on the cup support to drive the motor to run. It can only be activated with a pulse.

The one I purchased is a 120 volt. It does not chop up or blend strawberries even after I sliced them into smaller pieces. Also it will leave a few chucks of ice cream not totally blended

Our cup is 6.8 inches and the shaft length is 6.9 inches. If you use a 7-inch cup, only a small part of it will not fit. But please also note: If you don't use our cup, you may not be able to put the cup on the cup holder/cup buckle to automatically make a milkshake.

Hi, sorry I can not answer that question. I use it for making milkshakes and have never used it for frappes. I would question most likely not. I use the vevor professional blender for that. That is wonderful for frappes.
