What do u guys think of this dandy little device? the competition one to be exact

 

anyone got onr?

 

A lot of people have them. It's good for instant feedback on new mods, but it's not totally accurate compared to the track timing lights (sometimes as much as .5 sec off on the 1/4).

You really have to read the manual and understand the limitations and have a little common sense about car physics. It's a good tool to "see" gains after modding.
