thank you for being reasonable! I think throwing the voucher out would be just stupid too
Welcome to the insanity that is POTN... A lot of people here are quite zealous in their pursuit of 'perfection' and anything less is blasphemy. The white top Duracells will be fine and even the pre-charged Rayovacs compete quite well against the Eneloops. Only reason I have Eneloops is because I get them freeeeeeeee. I'd get the Powerex otherwise.
Even though we all would like the 'best' of everything, sometimes getting 'works for me' will do just fine. Some of us even use 'crop' cameras and not 1Ds bodies with 'L' lenses! *gasp*
