Saw this featured on Hypertunez, and then checked out the website as well. Its like a malaysian made broquet, just pasang the magnets near the fuel line and expect a miracle in fuel savings.of course, i also fell for it. so i went to get one. That accessory fella didnt know how to reach and pasang on my e36 318i fuel line, so I also fed up, I told him just give me that unit I will go ask my mechanic to pasang for me.Went to my mechanic, that fellow curse me babi-buta only. He said, 'allo friend, how can u buy this chow-h@! product. if work sure all the manufacturers pasang already man. i won't waste your time to pasang this, and also i wont waste my time'. There i stand like blur only kena maki. So then I went back to the accessory shop and got back my money.Sigh, so anybody else care to tell me if this product works??
