### ⭐⭐⭐⭐⭐ A good middle $ purchase.
*by C***S on August 26, 2025*

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.
