I installed this on
Mitsubishi Lancer

Review
The RSM is rather nice device to basically make my interior look pretty. The accuracy is accurate to a certain degree as it is highly depended on the input parameters, especially if the g-sensor is used to measure horse etc. It has a lot of functions in it and I set it to list 4 channels. It allows to tell me what the cars up to I.E.REV, Speed, Battery, Lateral G's. However, you can also switch to a channel to allows you to see only that specific channel clearly. What I love and attracted me to buy is the speed limiter function which allows to alert me when I'm driving in high speed.

What I like
Speed limiter function

What I do not like
It didn't come with stand.
