I have seen some products and reviews stating that some of these do work. I would like to know if anyone has any personal experience with any of these units or others or evidence confirming or defeating the tests that suggest they are effective.
I realize that many people have strong opinions on the topic of speeding and risking others well being but there is a discussion already started for that topic so please lets keep to the actual products themselves which is the topic of this discussion. I am not suggesting anyone speed in such a manner to expose others to unnecessary risk or danger.
One test I found that included among it the BLINDER MODEL M27 and M47 as well as the ESCORT MODEL ZR4 is included here for anyone to read and comment on to begin.
