Frankly for the price it is really fun! The software provided with very well (also used to configure the distances alertes..de to register a parcours..mise update etc). The concept "USB and cigarette lighter adapter is awesome!" The big point négatif..car nothing is perfect it is adjustable son..pas and I find it difficult to hear what is good ..but maybe my age (almost 40 years) and also the LEDs who does not see much. But considering the price I recommend !! Good trip at all ..
