Query: Brother GX-6750 Daisy Wheel Electronic Typewriter

This machine is horrible. It was very frustrating to operate and it does not work properly. I'm not sure if it was damaged during shipping, because the seller said that it worked perfect before it was shipped. I could not get the ribbon in easily. When changing the letter wheel, the machine would make a loud grinding sound. I was able to reset it once, to make the grinding stop. I needed to adjust it again, and then it started the grinding sound and I couldn't get it to stop. I would definately not buy this product used!
