I bought these awhile back before needing one. Did my oil change a couple months ago, wanted to wait a bit to review it. Fit is identical to the OEM filter, nice it also comes with new retention cap o-rings. Can recommend, seems to function as well as name brand/OEM and a good value since purchasing more than one. Literally got one for free compared to single purchase of 3. I drive my company 2012 Caravan about 35-40k a year, so I change my oil about every 3-4 months. I also have the upgraded all aluminum oil cooler, so I have to use this filter for the later models.
