this be we first gp and we love it . it do exactly what we want it to do which be get we from Ohio to South Carolina for we vacation without get we lose , send we way out in the middle of nowhere , etc. . we have have a lot of issue with use mapquest , phone GPS , etc in the past so we be concern about it get we lose in the mountain or send we to some tiny town in the middle of nowhere like last year with a borrow gp . we fully charge it before we leave and it hold the charge for 5 hour of constant use . we be not able to get it to charge or turn on by use the cigarette adapter , but we have a ac\/dc adapter in the car for my laptop so we just plug in into that and it charge just fine . the times\/miles be pretty accurate though it do seem to have a lag time if you change from the pre-planned route . I be sure there be other gp ' out there that offer a lot more bell and whistle , but this be perfect for someone who just want a basic gp with a simple interface . I also like that we do not have to buy new map and update like I have hear friend have to do . it do take about 90 minute for I to do the first update from the computer , but that be no big deal . I be look forward to use this on more trip .
