Contact with the phone terminals holds very well. Unlike others, I did not have to rectify the connectors of my Galaxy Note 2. Once the connectors held in place, just press a little on the card so that it adheres to the battery and remains in place (a sticker is located under the card for this purpose).
I was scared at first but I have managed to close my smartphone. The latter is fitted with a silicone shell (unsightly but necessary for me to not to damage it) and instead of being well dish, everything is very slightly rounded; This will not hurt anything, but this is evident by asking the phone flat. Before, he did not move. Now we can run it on himself.
The packaging was very light: just a plastic packaging. In fact, I almost threw the card because it was stuck to the bottom of a box containing several items.
Finally, attention to price. Ordered 6.45 there 5 days; Price just jump to 11.95 just before the holidays.
