Bought a new cobra for 100$ and sold it for the same price. Just got a used v940 for 76$. In great shape. I should of kept the cobra just to see the diference but I am glad to have gotten the v940. So far pretty much all comments have been good on this unit. I usually drive about 10km over limit . This is usually tolerated .I just wanted to know where the radar's are. In case I need to pass someone under the limit.
