A lot of times I just don't know anything about it. I enjoy researching them and trying to find out more about them.
Sometimes it's hard to know if any parts are missing or even if it works at all. I try very hard to look everything over carefully and to thoroughly describe each item to the best of my knowledge, but occasionally I may accidentally miss something. If this happens please contact me and I will do my best to make it right. I value my feedback and my customers, so I aim to please.
