long lasting battery
While the list price verges on the absurd, this battery does deliver as advertised and seems to me to have much longer life on a charge than the batteries I've been using with my Canon 5D. Amazon's prices on this item have been very competitive.

Canon LP-E6
What's to review? This is a factory original battery, so it performs exactly as expected. I am extremely happy with the price, 1/2 of what I could find it for locally. Locally however is in Canada, and since Amazon won't ship this to Canada, I had to ship it to my sister and have it re-shipped. Still, price worth the hassle. Amazon, when is your .ca store going to start carrying the same line of products? Or, when will you start shipping electronics to Canada, I don't care about the warranty.

Ideal Back up or replacement
I purchased two of these batteries to use with my canon 7D. At first I had considered buying off brand batteries due to the lower prices but after learning that such batteries were unable to relay information to the camera regarding how much power was left in the battery I decided to play it safe and stick to the canon brand LP-E6. I have used these batteries regularly as it extends my shooting times substantially without having to wait to charge my battery, I would recommend using this specific battery to anyone working in the photography field or looking to get serious abut their work.

It's Just A Battery
It works as any aftermarket battery with the same specs will work. Only difference is, you pay 5 to 6 times more for this one. The "reporting" feature is only there to force you to buy this battery, over the 3rd party suppliers that do not have that reporting chip. My Canon 40D shows the battery life, and it works with all 3rd party supplied batteries as well. Shame on Canon for ripping off loyal customers. They are starting to act like Apple.

I took 2 stars off because of the price gouging.
