All carriers have problems, and all carriers treat the packages more or less the same way, name one and I will give you a sad story about it....
Even we have heard some here, UPS is not the best, not the worst, simply another one of them, period, in some areas they are better than others, don't expect anybody that works for a salary like a beast, under heat or cold weather, and mostly under really bad working conditions, to treat a package in a decent way, my brother work for UPS and I know how the work inside UPS is, I have another friend inside the USPS, same case, they put the same care in a package that contains a chinese vessel of the Ming Dynasty, or an audio amp, or a jewel, or a box of nails...period, as most of the times they never knew what was inside the package,
If you want a really good service, use white gloves carriers instead, and pay three times as much, sad but true, that is why insurance exist, and why you have to package properly, and insure the packages, that is the sad end of the story....
