The site offers a tool to enable a features on car entertainment systems. After confirming my vehicle meets the requirements listed on their site, I purchased the tool.
The tool shipped from China and took several weeks to arrive. When it did, it did not work as described. The seller wold not respond to emails until a PayPal case was filed. At that point, after the contact window deadline nearly expired, the seller asked for me to return the tool (at my own cost) top Lithuania. The shipping costs exceeded the value of the tool.
