I bought these, good batteries, wasnt expecting alot longer battery life just wanted some extra batteries, if you are a power user dont expect to see a whole lot longer battery life. But they do give a little extra run.
As far as the actual company goes, Yes mine are genuine batteries, they should really make it so the instructions on the batteries them selves match the instructions that are on the card. Dont know if anyone else saw that.
Example, Batteries say charge for 8 hours prior to use. Card says 12. Card says kill to 1% before charging, the batteries dont.
Also the wallcharger....definitely isnt the worlds fastest. I can actually charge my phone while playing on it continuously while charging and it charges faster then the wall charger.
But hey, 2 extra quality batteries for 20 bucks. Still worth the 20
