    Item arrived exactly as ordered, just what I needed (couldn't find it anywhere else!), thanks 👍. It took about as long as one would expect, so no disappointment there. Finally, my only concern was that the coolant pipe poked through the end of the shipping package. It has some sharp ends on it, so may want to cover those better on future shipments. No points off from me for that though, good experience overall, I'll give the 5 stars & a thank you.
