Query: Major disappointment

I bought the 1lb fat replica and the 1lb muscle replica for display at my fitness studio and when I received it I have to say, I am majorly disappointed. I should have read previous reviews and saved my money. Not only is there not a dramatic difference in size (as I've seen when viewing a demo with 5lb models) but the muscle actually looks bigger. Also, When I researched to see if I could return it for a refund, I noticed it was drop shipped from a company called NASCO, which, had I bought it through them, I could have saved myself $25 on the purchase of the two. I gave this transaction 1 star because there isn't a 0 star option. I feel ripped off
