5 out of 5 eggsOriginal Product

Pros: OEM battery exactly like the battery that we are replacing. First battery lasted a long time and we expect this one to do the same. Works great as a stand due to the size of battery. Allows for better airflow under laptop, also.

Cons: Heavy, cuts into legs if you leave it on your lap a while. But we new this, so not really a con for us.

Other Thoughts: We received exactly what we expected. Shipping was super fast, as always.
