I have tried to checkout this item without the code you offer.
But, I got a message that it can't be shipped to my address.
So, is this product only available for Amazon US users only?
I'm not sure if it's US only, it works so long as you can ship to an address from the .com website since it can only be redeemed on the .com website. I wouldn't say it doesn't work for anywhere but US since amazon.com does ship to other regions, but not all items. Not sure what countries they ship echo dots to outside of the US, but it has to be redeemed on the .com website.
