This does work but not very well. I did get better when I put a smaller belt on it but it wasn't the correct belt so I took it back off. When the other belt was on it did not sound all warped like it does now with the loose belt on there. I for sure needs the one belt but probably 2 but I do not have the correct sizes here to replace them. This is being sold as is. It wouldn't be a hard job to do I just don't have the belts to replace them. The back is held on with 4 screws. I also noticed where you plug in the electric cord is a bit janky. Looks like it isn't in whatever its supposed to be in. It works the way it is so I left it that way. This would be perfect for someone that is just getting into repairing things. Pretty easy first project. Look at all the pictures to determine the quality of the item. If you have any questions feel free to ask.
