It was terrible
First off the customer service was great!! Five stars for them. The product however did not work at all in my 2009 Jetta. I thought it was a defective product so they were kind enough to send a new one, no question asked. They were extremely responsive and helpful. However after receiving the second switch that also did not work. Both switches were of poor quality. I finally landed up going to the local Volkswagen dealership and buying the product from them this was three times the cost but worked perfectly!
Sorry love the customer service but your product was crap!!
