1. It took a month to arrive. Granted, there was the Holidays, and dude is in Colorado so the snowstorm, but still. A month.
2. It was filthy when it arrived.
3. It's unusable for performance and almost unusable for practice because it only outputs sound through the right channel.
4. The auction said everything was in working order.
5. He communicated, but not very well.
Should I leave him a negative feedback?
