Summary: The only early inhibition I have is that the machine seems to labor when sewing through several layers of material. But, perhaps I am exceeding its capacity since the fabric was a very tight fit under the presser foot.
Summary: I bought this machine thinking the self threading feature was a great idea. But on first use, I found the average reel of cotton does not fit the cartridge and I spent many miles and hours looking for cotton to fit. The only reels that fit were the really expensive ones. Self threader threads when it feels like it which is not every time. The bobbin winder doesnt wond the cotton on evenly and you have to help it wind the cotton on to acchieve a better result.
