Is my used BABY BULLET broken? HELP!!!

I just purchased a used baby bullet. It came with everything except the steamer and spatula. No biggie! I just went out and purchased the steamer. I was so excited to try it!

I steamed everything and when I went to purée the food in the baby bullet blender I found it was SO HARD to press it down and turn to blend. I literally have red marks all over my hands. How hard is it normally? When I watched reviews it looks so simple, using one hand just gently push and turn? But whenever I do it I have to use all my weight (literally 😂) and push as hard as I can and turn it. I also have to hold it down or else it stops. Is that normal as well?

I’m so upset and disappointed. I’m not sure if it’s the product or the person who sold it to me.
