Comparable to the rechargeable batteries sold by Microsoft.
Fits fine in both the controller and the charging station I have. The battery play time is just about the same as the official Microsoft Rechargeable batteries.

This battery still holds a charge as well as my official "Microsoft" rechargeable batteries. When I bought this battery, I bought a brand new "Microsoft" battery as well and have been switching back and forth using each one until they die as a test against this unit's capacity. I will never buy another Microsoft battery again when presented with choosing this battery or an "official" one.
In retrospect, the only con about this battery is that it doesn't sit "flush" with the back of the controller. I figure that since the majority of my time spent using this battery involves me looking at a screen, and not the controller, this is so minor as to not affect my future purchasing decisions in a negative way.

Sadly, my NYKO battery refuses to hold a charge after many hours of providing the much needed sustenance my controller requires in order to carry out my commands via button input.
In reference to my test of this battery's capacity against a "Microsoft Brand", the Microsoft battery still holds a charge (although a very diminished reserve that requires a recharge every 3-5 days when I spend a few hours gaming each day).
When I wrote my original review, Microsoft Batteries were nearly double the price of this 3rd party battery. I hold to my original review that NYKO made an excellent and cost-effective product, but grudgingly acknowledge that the Microsoft brand battery outlived (and essentially outperformed) the NYKO in tests of longevity.
In short, if you can find a good deal on an official battery, go for it. Otherwise you can expect to get your money's worth on a NYKO.
