Got this to replace my 3 year old battery. Laptop is still in good shape except for the battery. Now it's better than new since this battery lasts longer than the original one did when it was new!
I have had this piece for more than a week now, and I have not had any problems with it. So far, the power-rating is good, and the battery fits in tightly in its location. There is just no need to waste money buying similar battery from Toshiba.
Charges quickly, lasts a long time, fairly light. Do yourself a favor and run the battery down instead of leaving the laptop plugged in all of the time. These batteries only last 12-16 months with any moderate capacity, and will last longer if you don't keep them fully charged 100% of the time.
