I have my old EeePC 1001HA can no longer be used because its battery has failed. The device never had a term of more than four hours, so I looked around for a 'cross-country skiers'. With this battery I bring it to 8 to 9 hours, therefore good results at good price. 5 stars I will not give, because maturity also has its drawbacks. The unit is now much more difficult and you can only 'bent' operate because the battery was increased downward. For me, this has little significance, the primary application of the PC in the living room. But who goes on tour with the part, will have to weigh the long term with the weight and now 'pocket unfriendly' form. Finally, a comment for the supply: arrived on time, no problem, 'my account' but has not been updated in.
