Still working great!!
I really didn't have a good feeling about ordering a starter online, but I was in a situation where I didn't have the time to get to the auto shop before my day off and Amazon could get me this part just in time. So I reluctantly gave it a shot. When it showed up it had a couple of small black pieces of plastic loose in the box similar to the pieces shown in another review on here. It didn't look like they from anything functional. I really needed to get my wife's car running so decided to install it anyways. The install was easy and it was a perfect fit. The only draw back would be that the signal wire didn't click in place like the signal wire on the original starter. But it was a snug fit. It has been installed and working great for a month now. Very happy with my purchase. It also had a message from the seller when I opened the box giving the starter a 2 year warranty. Very cool. If the starters fails in the next two years I'll get on here and edit my review. So if your reading this then it is still working great.

Great quality at a great price too!
Husband got this for his ‘05 Camry and says it looks and fits just like the original. He was happy that it simply slid in with no adjustments needed. It’s been a couple months now and no problems at all. Very satisfied with this item.

Electrically good. Fitment not so good.
This starter worked fine when installed. The only reason I didn't give it a 5 star rating was fitment. the hole in the bell housing is slightly larger than the starter. The old starter, OEM, was a right fit. This puts all of the strain and torque of starting the engine on the two bolts that hold the starter in. I expect this to fail at some, hopefully, distant point in the car's future. In order to retorque the starter bolts, the battery and airbox have to be removed.
