The rubber feet seem fine to me. The thing I am most concerned with is in the bobbin case theres a latch/button something that is a cream plastic with red circles on it. I'm not sure if this is supoused to move or not? I tried (and it looks like my mother tried) to move it but it didn't budge. So if it's not supoused to then were good. If it is supoused to move then I have a problem and I'm not sure if it's big or small. Haha
