Pros: Superfast, Runs Cool, Solves Many Issues

Cons: None so far. Sure, the price seems high, but it's worth every penny.

Overall Review: Perhaps I should wait longer to review this, but I'm too excited. This is my first SSD. It has surpassed all my expectations. Every other review is focusing on the speed. It is incredibly fast. The boot time alone is now a fraction what is was with my old hard drive. Photoshop loads in seconds. The best improvement by far is temperature. My overall computer temperature is 15-20 degrees (C) lower than it was. That's a huge improvement. Also, knock on wood, nothing at all has crashed since making the switch. NOTHING. That can't be a coincidence. 240 GB is a major step down capacity-wise from my old 500gb hdd, but that's why I have an external. All my junk can go on there, an I'll use this for essentials. Great Buy, Highly Recommend!

Pros: It works just as well as the Dell OEM battery.

Cons: It doesn't work any better than the Dell OEM battery.

Overall Review: I wish I could give this 3.5 eggs. I chose to round up. I haven't had the battery very long, so I can't review its lifespan. What I can say is that out of the box it isn't amazing. Fully charged, running power save settings, I'll be lucky to get 2.5 hours - tops. I typically get around 2 hours. If it's fully charged and you unplug it you'll see an immediate drop from 100% to 96%. But, this isn't much different from the battery Dell sent me with the machine, and this one is cheaper than a Dell replacement. I chose LB1 over other brands after doing a massive amount of research on all the brands here on Newegg. I haven't had any contact with the company, but this shipping was super fast. Hopefully I don't need to use the warranty, but you never know. I do recommend this, but limit your expectations. If you want 4 hours of use - buy two XD
