Just wondering if anybody uses these things and if so, how accurate are they.
they are going for only 35 bucks on ebay, so was considering picking one up.
but don't want to waste the money if it is a joke.

theyre arent completely accurate an definitely no substitution for a dyno. however, they are pretty consistent, so, for example you can use it before and after a modification and they are pretty useful in showing you how much difference a part makes for your car.

 

thats what i wanted to know, thanks
