I'm pleased to tell you that it's half true. I didn't bother photographing my left hand because it indeed is chip free! My right hand however (which is my dominant hand ), does have a couple nicks. Below you can see the evidence.
My verdict: All in all it's a pretty amazing polish. If your nails tend to chip as easily as mine usually do, it definitely lasts longer than a day or two. For those whose nails don't chip much, my prediction is the polish would most definitely last one whole week for you....chip free!
