Purchased from We Sell Bulk here on Amazon and received the item much faster than predicted delivery date - I only say that because there's always a list and it's often difficult to pick which seller is the one to go with. Anyhow, the battery came in original and undamaged Canon packaging (looks just like the images available in product description). I was not about to buy the cheap knockoffs and was worried that the one I ordered would be any different than the one that came with the camera (damaged item or store return). Well, after a couple charges and hundreds of pictures, I can say that this battery is exactly the same as our original. It lasts just as long and charges in the same amount of time. Our camera is fairly new so it was a fair comparison - one battery wasn't all that much older than the other.Email me with questions: mister_mr_d@hotmail.com

I am a huge fan of the Tomb Raider series, and have played all five other games on my PC. I love them. I was so excited to get this one, and sooooo disappointed with the quality. Glitchy glitchy glitchy. Do not buy this game. The controls are terrible. While all other 5 games play out smoothly, this one is slow, stalls, goes blank some times, and takes minutes to load to new chapters. Now I don't have a fancy schmancy computer, but I have been able to play all the other games on it just fine without any hitch. This is just crap. It makes me feel like I have to go buy a $2000 computer just to be able to play this $30 game! It probably runs better on a PS 2, so if you have one of those don't bother with the PC version. Thanks a lot Eidos, I totally wasted time and money and am warning future buyers to BEWARE!

Intellectually and artistically roughly on a par with the Flintstones. Despite the numerous five star reviews it has received here this risible prehistoric bonkbuster is utter dross, a hopelessly 'eighties modernist' take on the past diplaying minimal knowledge of human nature and the way new ideas and societies really evolve.Of course good fairy tales can be entertaining for children and adults alike and are an esential part of our cultural heritage. Not this one though
