So far this little machine is working perfectly. I had read reviews where people said that it operated in its own without pushing the foot pedal when it was switched on. When I first opened it that was what it did however once you read the instructions you find out that to use the foot pedal you leave the switch on OFF. 
I am a seamstress that does alterations, etc. for other people and there are times when I have been at work and wished I had a small machine. Now I do!
