The part was good and arrived in a timely manner. However due to my own error I ordered auniversal part without the pigtail.

I prefer not to use this type of part as it is easy to mess up. Make sure of what you order.

My overall experince with Parts Geek was good and I would not hesitate to purchase from them in the future.
