Pros: Cheaper than a Toshiba branded battery.

Cons: Lasted less than six months of very light use. I only used the laptop occasionally during that time and battery wouldn't maintain a charge between uses. I didn't think too much of that until the battery stopped taking a charge at all. Now, Newegg won't replace it (past 30 days) and the manufacturer wants $15 to replace it under warranty. That's more than 20% of the purchase price (on top of that, I have to pay to ship it to them). Some great warranty, huh? At least the Toshiba branded battery lasted three+ years.

Other Thoughts: I gave it one egg because it didn't arrive DOA. The manufacturer, Lenmar, seems to not worry about getting repeat business. They won't get it from me.

Pros: Bought it for a client's teenage daughter and she claims it is powering her laptop fine and charging normally.

Cons: None yet noted.

Pros: It lasts long. Lasted me about 3 hours without charging it.

Cons: Used money to pay for it. Hehe.

Other Thoughts: The battery is actually 4640mAh, not 4400mAh. Which is great. Also keep in mind not to charge your battery while using it.
