Great Product
I use it for my work headset, eight hours a day, never dies during my shifts. I charge every evening after work. Best product for the price!

Works great
This was easy to install and does the job it says it will do. Now I can use my headset all day without having to recharge

Works fine
Battery is perfect fit for my headset. Easy to install. didn't rate "Sheerness" because I don't know what that has to do with a battery, and didn't rate "Battery life" because I've only had it a few weeks.
