I've had two recent recent major gripes with UPS. The last two large items I've received from them have been blatantly miss handled.
The boxes are extremely beat up as if they'd fallen off the truck several times. For example, the computer I purchased was dropped so hard, the hard drive and ram had come out their mounts/slots. This went to claims which took over 3 weeks to finally get a refund. The most recent box was packed well originally with lot of the airbags and paper padding, but had been beat around so much that all the airbags were burst and the parts inside were banging together.
I'd advise this, to anyone reading, if you have a valuable item to ship, just use USPS Priority Mail or Parcel Post. They are all I have ever used to ship items out and I have not had one single problem.
