This might have been a good product, but because of either the fault of the post office, or the fault of Amazon,I never received it. I was given such a run-around between Amazon and my local post office that eventually the item was sent back apparently because of an "insufficient address" even though the first message I received about its attempted delivery noted that delivery was attempted but nobody was around for signature (even though I had it sent to my government work address, where someone is ALWAYS available to sign). After a lot of back-and-forth and waiting, the item was ultimately sent back and when I called Amazon to ask if they could ship it back to me, expedited, they said they could not -- I would have to wait until the item was processed in their returns departments and then put back on stock, and then somebody would call me to tell me it was back in inventory so I could reorder. I never received such a call. I am extremely fed up with Amazon.
