The best part about the Navigine SDK is its accuracy in terms of location and route calculation. It has been used for our application to calculate the routes and locations for the customers. We have been using this SDK since last 3 years and it's never failed us. I would definitely recommend this product to my friends and colleagues who are looking for an accurate tool to calculate routes and locations. It works well with our application and delivers accurate results. The only thing which I dislike about this product is the price factor, but that doesn't affect the performance of the product. We use it in our application to provide the users with accurate locations.
