Based on my experience, this ratcheting serpentine tool has been a game changer for working on my car belts. The compact design allows for easy access to tight spaces and the ratcheting mechanism saves time and effort .The 11-piece set covers a wide range of belt sizes, making it a versatile tool to have in the garage. The only downside is that it may not work on all types of serpentine belts so be sure to check compatibility before purchasing. Overall, I highly recommend this tool for any car enthusiast or mechanic..
