I personally had with the model Black II problems with the magnet. (All other cases are SUPER) My Nexus 7 and had my wife constantly dropouts and display went out. Very, very important: seller has written to me to my original review and asked me gently (if necessary with a lawyer!) To delete it and do not write, I d advise against this product.. So to all those interested. Continue to buy this product, if necessary, they can indeed return if the problems should have it.
