I like that it's easy to use, you can input any information as needed (i.e. vehicle make/model number) so there are no errors or omissions of data entry. When we have an issue with our truck, the customer service is outstanding - they promptly call us back, fix whatever was wrong and get things right again! We don't have anything negative about this product at this time. If you're looking for a simple system that works well, then check out Spier Link Check & Drive.
It has been working greatβ¦
