Review: Quality Part! Great Fit! - Great fit! Quality part! Much better than the 25$ one I bought earlier that didn't fit. Seems to be holding up well too!
Review: A good middle $ purchase. - Got this because I hate the cheaper brands (not naming names). So far it is holding fluid and is clean and durable. It fit right onto the Jeep, a Grand Cherokee Laredo 2003. The sensor fit right in snug and it looks great. It is so far worth what they had it priced at and so far it works great.
