Query: disappointing

Being a long time fan of Monroe products, I purchased the Sensa Trac shocks and struts. About three weeks after installation, I noticed one of the shocks was leaking. I know that things happen, but when I was unable to return the defective part for a replacement, I was not happy. I ended up buying a replacement shock through a local parts store and ended up paying twice for one shock. Be sure to check the return policy BEFORE you order from Amazon
