i personally liked it, but it just gave off so many false alarms and such... for the price of the radar and everything, i was thinking highly of it and i was very disapointed in the end. i think im just gonna go ahead and get the v1??? but the 8500 just gave off so many false signals, i just started to ignore it at times... and on l'vill suwanee road and 85... before the overpass... i got all types of signals from the chevron passing it. i was like wtf? who knows
