This product is really handy in combination with a coyote for example. The speed display is very clear and legible (if you put the patch otherwise !!! sunlight you forget ...). The satellite search is a bit slow cold (1 min) if you do not have a full vision south. A hot in 15 seconds it's done. Installation is really super fast and the pellet is easily glue (tip: position tests made in relation to your field of view and mark where you want to install the patch, it will save you time) Having the HUD is really convenient, your peripheral vision tells you your speed, you do not have to leave the road ahead. Sometimes a few tenths of a second of inattention to read your speed on the counter of your car can cost you. One (big) downside, the limited battery life, in 1h is empty! The cable is not very glamorous but hey, if your ride is not very long, you can just load it with any USB / mini USB on your PC before you leave. Would recommend for this price!
