It's a good alternative, since Mopar stopped manufacturing these 4-pin relays. desertcart's system says this relay does not fit a 2007 Jeep Liberty, but I knew that wasn't true, so I bought it. Only time will tell how good the quality is. I will update this review if anything happens. In the photo, you can see the old Mopar relay that I replaced.
