Peter already covered it, but their tracking really is pretty much useless. It's because it's simply meant to confirm that delivery has been made. For me, it's done that flawlessly.
The extra little bit of "tracking info" is just a bonus. Most of the time that part doesn't work for me at all, so I seldom even bother looking at it. At most, I might check it the day after something is supposed to have arrived just to see if the package made it.
