I installed this on
Honda Civic

Review
This may have been the most valuable item for my car I've ever used. It is almost versatile for almost all car engines. This means that it would be of good use for those that change their rides often, like me who gets bored of a car easily. It also is long lasting; I had been using this coming to 3 years now. Another awesome feature of this device is that I realized with using it, gear shifting were a breeze. I had compared the performance of gear shifting with and without this device, and I can definitely vouch for its smoother gear shifts ability. This device had eliminated most problems that I face such as my heavy foot on the gas pedal for low performance cars, over acceleration on slopes etc. Recommended to ALL the drivers out there!

What I like
The awesome features packed in a small body. Fantastic for all drivers.

What I do not like
Expensive, and most drivers may find it unnecessary.
