I backed Coin on kickstarter, and am yet to get mine. It was supposed to be in my hands in November after delays, and now it is nearly January and haven't heard a word from them.
I pre-ordered several coins in November 2013. I tried to retrieve my Coins during the beta, following through their convoluted "get an invite to our iOS app to request your coin" process. I did not receive even one coin. I have not heard from them since August. As far as my opinion is concerned, they're frauds.
They did have the courtesy to email me before Black Friday and offer me $1 off more preorders, though.
I've seen at least one "Coin Beta" backer that actually got a Coin. It looks like a credit card - the button does not have a great clickly felling you would expect and the quality does not feel premium. but it seemed to work.
Same story here.. I actually 'ordered' two (one for my SO), and applied to be in their Beta. I still have an iPhone 4s, so they have about 2 months to ship it before I upgrade to an iPhone 6 and never look back..
Note. Shipping notice does not actually imply actually shipping, as I just discovered from their customer service agent. It just means they've created a shipping label for you and some time in the future (exactly when he didn't know) it will be used to ship you your coin.
