I have absolutely nothing negative to say about this RamPro oxygen sensor kit. This is exactly what I needed. I was looking to fix my 2001 Honda Accord and came across Revain. The price seemed reasonable and saved me a trip to the mechanic. I had to get rid of the check engine light. After using my diagnostic code reader, I found that I needed to replace my oxygen sensors. I was able to get my oxygen sensors out easily with the RamPro. The sockets fit perfectly on my 2001 Honda Accord with 3/8 head. I am very happy with this product as it saved me time and money going to the mechanic.
