Review on TGU Tennis Gifts Hands Free NIS022132025 by Jason Carranza

I don't have another speedometer to compare. I don't always get the same number with the included audio plug, so I think there are some differences. However, the biggest problem I had with this unit is that it seems to pick up some of the signals around the tennis courts (I went to two different public courts, tried day and night when the lights were on), so that's what causes the speed constantly appearing for no apparent reason. This works to be found in my backyard. As I can't use it on tennis courts as it picks up some weird signals I may have to return it.
