No problems with this unit other than the ubiquitous "low battery!" warning which I have found over many years of use (of my other AW) to have no effect on the operation of the unit. This unit is the one I have kept as a spare. Will ship in an original AW4416 shipping box though it may not be the original box for this unit because I've purchased several over the past ten years or so. It's fairly large and heavy so I would imagine shipping will probably run at least $70. so that's what I'm asking for shipping. I really doubt it will be less but if it is I will refund the difference. I am jamesarts on Ebay and if you like you can check my 100% highly positive feedback over more than ten years. I highly recommend you also purchase a Y56K Waves card which is made for this recorder if you can find one at a good price. It gives the unit much more capability for mastering. I will ship this item to physical street addresses within the 48 contiguous United States only - no exceptions. This unit is accurately described. It works as it should. No returns. Thanks.
