I love this machine. Best thing I have bought in my life. It runs sooo quiet and smooth, like a hot knife through butter. I am even tempted to go for an industrial overlocker now. However, setting it up was a nightmare for me because I am a first time user of an industrial machine. So I highly recommend and urge you guys to include a 1 hour lesson on how to operate the machine, include it in the price. A first time user who is struggling to operate the machine might end up even thinking there is something wrong with the machine
