I've used the tracking for locating some packages that had delivered by the USPS, I wasn't impressed. They do track the package, but it doesn't give a lot of detail about real time location's, or where the package is located at the time you put in the tracking number. They say they are hooked up to google maps, and it can give a location for where the package is located in real time, but it doesn't work, at least on my phone it doesn't. Also I have a real problem with informed delivery, I get notices that give me wrong date's, time's, and location's sometimes, I can definitely appreciate that a package might have delays, but if it's supposed to be delivered on the day that the USPS says, then I think and prepare for it to be delivered on that day. I've been informed of a delivery in the morning, only to not only not receive the item, but it shows up the next day, instead of what then informed delivery says, and USPS wants customer's to use the service, well it's not accurate, that's only in my opinion.
