Not familiar with these. Seems like more work than just polishing your nails.
I guess I like the natural look of real nails, not the fake tips or acrylic nails. I can see maybe doing nail tips for a special occasion, but for me, fake nails are not very practical for daily functioning. One thing I cannot stand is the long, garish witch-woman nails some like to sport. I know a few women who have nails like that and they are not attractive. Not in style at all. Besides, they seem very unclean and just watching them touch things with their nails is gross.
