I bought one but could not get it to work that way because of the way my machine is made. It angles back towards the needle, not straight down like most machines so the laser won't point the way I want. Because of the slant, I sew with my face tilted closer to the machine to see the needle, and was afraid what the light could do to my eyesight. I have seen it set up with a machine that is straight in front and it works great.
