The Walmart Brother machines are awful. They give Brother a very bad name and I really wish they would stop selling them but oh well. I have a Brother QC1000 and a Brother serger . Got them together on a special a few years ago. Never had any problems with them And I use the machine almost every day. The serger has been used quite a bit for making crate pads for dogs. 3 layer, flannel, batting and cotton. Not a problem. I love my machine.
