These batteries have performed no better than ones I bought in Lidl ie; not good! 50 photos and 5 minutes of video with an Olympus T10 compact digital camera on a Saturday .... and they're dead. And that is with using the new £14 Energiser Battery Charger.
I'm up to Chapter 4 and finding the text difficult to follow. The story-line doesn't flow smoothly for me. Punctuation is unusual, commas and full-stops all over the place. There are some spelling mistakes too. I'm thinking the book was rushed for one reason or another.
