I have not used the shaper because I'm trying to decide if I will return it.  I ordered the top and bottom. But, was only sent the top with the explanation that only the top was not included. I emailed the company and they said I was told it only included  the top. The only time I was told this was when I recieved the order. I looked carefully at the ad because it was cheap and the only one that included both top and bottom. I probably would have bought it any way because it was cheaper than the others listed. But I felt decieved because I think it was sold under false advertisement. I paid to have it shipped and I would have to pay to return it. So I guess I will keep it. But I will not order anything else from Southern Traders for fear I will be DECIEVED again! I don"t know if it works because I have not taken it out of the package.
