    I would recommend looking at their shipping times, I didn't read that part well, my husband was in a hurry for a part and had me look and purchase on eBay. After a few days it hadn't shipped so I contacted them and I received an email that they made a shipping label for it and then they shipped it a couple days later. So a bit slow on that. Part though was just as advertised, worked perfectly in the engine and is going strong! :) It was packaged well and a good price!

    I am leaving positive bc item was as described but very unhappy that shipping took so long. Purchased on the 1st, not shipped until the 12th and delivered on the 15th. They did communicate after I messaged about no shipping update after a week. I was told shipping takes 2-7 days. Mine was 15 days from Texas to GA. It would be nice if they told buyers up front about the delayed shipping because I would not have purchased from them knowing it was going to take so long to receive the item.

    Well priced. New item. Received fairly quickly once contact was made to company requesting an ETA. Arrived well packaged and great quality. Good seller.
