Price and delivery: unbeatable, was after three days because
Function: works perfectly (for 2 months, it will be really interesting probably only after one year); as mentioned in previous reviews, the term specified is somewhat capricious - in fact it has leveled off with a fully charged battery in 8-9 hours, which I find very comfortable and never had to fully exploit, although I much use my netbook as a working tool. ,
Handling and optics: the battery can be used easily and take out and remains securely in the anchorage. Also as already mentioned several times, it increases the netbook by a few centimeters, which does not bother me personally when working. In fact, my netbook is now a little heavier - but for the long term and the price, I'll take that gladly accept - 500g is now not even the world. As for the optics: I find my netbook anyway not particularly stylish, hence making the battery a little klopsige the matter even worse. (If you did something right Chic, one may feel the different). A colleague who has the same netbook has only noticed the change in my schedule of the week, and that too only when the two devices side by side were times directly on the table.
Conclusion: Who are price and long term more important than the original appearance and weight is with this battery very well served. I can not say anything about the battery life.
