Shows plenty of signs of physical wear, but both lights did turn on. First the red and green solid then when turning the knob to get it going the red would flash as it heated up. Machine got hot and appeared to be working, but this is being sold AS IS with the only knowledge I have is both lights did show to light up, the red one was able to flash, the lights shut off like properly when the lid was raised, and it did get hot and the heat was present. If there are any other parts or accessories to this I do not have them. Other listings I have noticed have a thick felt type piece that goes on the inside. I DO NOT that and it is NOT included. Therefore you are getting this unit that both lights light up and it heats up. That is all I can confirm to work on it. Any questions or if you need me to do any other tests let me know.
