Despite knowing well and trying hard, my wife still gets it wrong at times. As one gets older, eyesight changes. Besides, not every device has symbology that is entirely legible, either. A few have given me a struggle just to find them. Some are quite easy to read. But not all by any means. Not that I'm arguing for or against, here. I just don't find the above a particularly good argument against it. >Like putting an automatic choke and electric start on a chainsaw. >Watch how many people cut their limbs off. I lost a limb (finger tip) using a device I'd been using safely for more than 12 years of routine and regular use and knew extremely well. I'm not supporting automoatic chokes and electric starts on chainsaws, either. But your argument here is non sequitur. Jon

How many people see the > embossed image and still get it wrong? I've hit the age (53) where my near-vision is going. Seeing that embossed image (especially when its only embossed and there's no black-on-white or white-on-black outline) is getting more and more difficult. So yes, there are a bunch of us to whom that embossed image is becoming less and less of a useful guide... While I think this idea is pretty cool, it isn't clear to me that, in practical terms, it's actually better than the various holder designs that make it hard to put the batter in backwards or that won't make contact if you do. -- As we enjoy great advantages from the inventions of others, we should be glad of an opportunity to serve others by any invention of ours; and this we should do freely and generously.

Well, if I have to replace the four batteries in my digital camera in a dim environment, I really need my reading glasses to see where the + and - markings are. Being able to just "throw" the batteries in the hole would be a great thing. Meindert

If you are "replacing" batteries isn't it just simpler to remember how the ones you have just taken out were positioned? tim

Not if they're inserted vertically. I'd have to feel which ones have the + on top without glasses.... Meindert |
