Review: So far so good.. - It works perfectly, sound better than OEM,little loader that I like. Price so affordable and quality. thank you China....so we can affordable those inflation nation.
Review: Absolute rubbish – snapped on first use - I bought this for my Mercedes ML 63 AMG, expecting it to at least function. It didn't. This thing is total rubbish. The quality is incredibly poor—it broke the very first time I tried to use it. When you're dealing with an AMG, you expect parts that can handle the job, but this was a complete waste of money. Do not buy this "product"; it’s a joke.
