Customers appreciate the ease of installation, speed, and value of the auto part. They mention it's easy to install, runs smoothly, and is a great product for the price. Some are satisfied with the power. However, some customers have reported that the CDI doesn't work and some parts don't work. Opinions are mixed on the build quality.
