I have it and I'm satisfied with it. I don't know how accurate the measurements are, since I haven't gotten any others to compare to regarding BMI and so on. But it shows trend of how you are doing and I think this is reliable since if it is wrong it will always be wrong in the same way. If you keep that in mind I think it will do a great job. Also, I find it very convenient that it automatically syncs with Garmin Connect, so I don't have to write anything down, I just step on the scale in the morning and continue my day - it is already saved.
