    I ordered the same alternator from this seller twice. The packaging this time wasn't as good as the 1st because there was only bubble wrap protecting the alternator in the box. The bubble wrap popped so the alternator was resting on the bottom of the shipping box with no padding to protect it from damage. The seller should wrap the alternator in cardboard, then wrap that in bubble wrap then placed it in the shipping box. Other than the packaging, the alternator seems to work fine.
