Dependable Performer

Written By Henry, Upstate, NY on Thursday, April 11, 2013

Crutchfield Customer Review (What's this?)

I've been satisfied with this battery since trying it after using some 3rd party cheaper batteries. This one lasts longer, with no degradation in performance (using the flash.) Although the price seems expensive, it's worth it when you don't want to compromise performance or have the hassle of it giving out when you need it.

Pros: Good performance, lasts a long time, easily shoots a couple hundred photos without a hitch.

Cons: Pricey but compared to the 3rd party "bargain" alternatives it's a no brainer, cheap batteries = subpar performance.
