i saw one testimonial on a guy with a gtr

 

well i guess that's a no. I may buy some and let u know....

 

i dunno. if that technology is good, why aren't OEMs using it? doesn't seem to be expensive so i doubt it's the cost factor. makes you wonder.... the range of 5cm seems to be low. i mean, that's like 3 inches. i think a 5-10in range would be ideal
