Sony dropped the price on this considerably so I had to pick one up for my 13.3" S series Vaio. It doubled the battery life from 4 hours to 8. Yes, it obviously adds weight and bulk but it's actually not that bad. You can always take it off on days when 4 hours is enough and you'd prefer a lighter load. I just leave it on so I don't have to worry about my battery running out. This has been very convenient when watching Netflix because I don't have to be tethered to the charger since the battery lasts so long now!

I'm a professional. I need to be able to be on the go constantly. These battery sheets are able to be dropped while the laptop is running so all I have to do is thumb the latch to drop the spent battery, slot in another one, and I'm able to keep going. When the dust settles, I can toss spent batteries onto the charger independent from the laptop so I'm completely free from the tyranny of the wall outlet since one slice give 3 good hours and takes 3 hours to charge.
