I have never before had a power cord wear out on me, and this lovely little device has decided, after 9 months of use, to point at me and laugh, in the form of making me spend approximately 1 hour repeatedly adjusting the cable position on the floor to allow power to reach my laptop. for the past month, I have only been able to recharge my laptop at home. However I recently made the colossal mistake of coming in contact with he power cord while working. This appears to have angered the computing gods, and as such I have been unable to get any delicious electricity to my starving laptop. 1 out of 5 is praise considering what this product should be rated, especially if you take into account all the other reviews of Toshiba power cords dying after only a few months of use.
