First set of 4 was packed poorly in a oversized box with nothing between them. Not surprisingly, they got jostled and 2 of them were damaged, seals broken, chemical everywhere (no, it's not hazmat). But in typical amazon fashion, they hustled out two replacements free of charge, and just a quickly. So the 5 stars is for service. As for the product, I put them in a basement with dehumidifiers running to, so who can tell?

BUYER BEWARE !!!! Quickbooks charges you ($79)from day one to support the product. The first time I went to use the product it failed. I called support over in the Phiippines and before they would look at the problem they need $79 dollars. Now mind you this is a problem on day one. I then called the corporate office, and talked to Terry and she confirmed NO $ MONEY NO FIX!! I explained again this glich is in their product on day one. I asked to talk to her manager and she responded she was the end of the line in the complaint department. I asked to have Brad Smith whom she said was the president to call me back and she said he will not talk to customers. That leaves the customer knowing that he doesn't care about customers or that there are too many complains to answer. Is Amazon ok with selling products that the vendors will not back? Check it out for yourself call Intuit Quick @ 650-944-6000 and ask for Brad Smith.
