I'm posting this in case anyone else purchases this gear and thinks they can use it like the original battery that comes with the Note 3.
There is another post in this forum that talked about a 50% off code until June, so I bought this:
Even with shipping/tax, it only came out to ~$31. I thought great deal.
It arrived and I noticed that you can't use it like you would the original Note 3 battery where I stuck a Qi-enabled sticker on it and could use it to wirelessly charge my spare battery when the main one runs down, figured I'd just buy another Qi-enabling sticker.
Thing showed up and it's NOT Qi-compatible. Meaning, it has no contacts on it that let me attach a Qi sticker. Not sure if it's by design that way but just thought I'd provide a heads up in case anyone else is looking to buy this.
