With my laptop I have been always satisfied (now upgraded with 8Gb RAM and SSD). The only restriction was from the outset the limited battery life (1.5 hrs.). Therefore, the decision to a replacement battery with more capacity. For battery itself (duration, durability, etc.) I can currently say little, because only recently in use. But installation was very easy, and secure a locked tired, no wobbling, rattling. The processing makes a very clean impression. As already mentioned in some recessions, the laptop is behind a little high by the battery. Do not bother me really, since the keyboard is thus "user-friendly" chamfered and cooling works better (less noise Duch the fan).
Here are a few words to the seller: I got an email alert to shipping, with information for the forecast delivery date. Unfortunately no information is for commissioned parcel or shipment tracking included. This moved me after the vorraussichtlichen delivery to demand. Here was very responsive and I got the information only hours later, very friendly and competent by email (on the same day the article was also supplied). Therefore I forgive here 5 Stars. Small tip still on the company B & W:. Mitliefern Wherever possible, shipment tracking in the first notification equal :-).
