Do Ergonomics Sell Product?

I was at the grocery store recently and needed deoderant. The oddly shaped bottles of Secret attracted my attention for sure, but really. Even though the bottle fits both right and left hands beautifully, AND contains less, will NOT make me purchase it. Would it improve my 'experience' of putting on deoderant in the morning into some life-altering one? Lemme think about it... Other companies are guilty of trying to make their product more 'sexy' by adding ergonomic features. Take Banana Boat. 'Sure, let's throw some grip indentations on it so when you have the slimy lotion all over your hands, you don't drop the bottle!' There's a catch though consumers, lefties may need to turn the cap around...er, if it will move. Hmmm...
