I have had this unit for four months now and have not had any problems with it. Some of the things are not very intuitive so you have to read the manual from time to time, but after you get used to them, the unit works very well.Accuracy seems to be very good.I have dropped it on concrete and had it skid across the sidewalk and it came out unscathed.I use my receiver for geocaching and it works really well for that. I have not tried using it for finding roads or addresses or anything like that.
