I am extremely happy with this battery. I noticed that the generic brand offered a max of 400 pics per charge. Whereas with this battery, I was able to take about 1200 pics in one charge. I took a combination of pics with and without flash. I mainly bought it for backup for when and if my battery runs out while I'm taking pictures at parties, outdoor activities, etc. It has come in handy and holds it's charge well. I believe this battery is well worth the money spent on it.
