The way I tested these clocks was putting them in my system for a week then I put them out in my car. Then listen to the same CD's again for a week on my home stereo system. This is the best way to test these because when you take these clocks out of your system and put them outdoors the effect stays in your system for a while so you can't do a quick A/B test to see whats going on.
