This product lasted less than a year in my Mercedes, I gave it 5 stars in a previous review but I remembered it. Now I give 2 stars, the seller really don't bother to answer product warranty complaints and you will feel the long warranty form on another website and you will be under their dirty warranty statement. This indicates that this seller (shockwarehouse) does not have a backup copy of this product. I will not recommend this seller, this product can be good and how long it can last is a big question mark. I can buy it again but definitely not from that seller above. Buy from the Amazon marketplace or from the manufacturer of the product itself and save yourself the hassle.
