Being a geocacher and avid GPS user, I just had to buy the SEPHORA by OPI Nail Colour in the shade Lost Without My GPS. Plus, I really liked the shade when I saw it in the store!
Turns out that this is not only a great spring/summer shade, but it lasted incredibly well for me. I wore it through a weekend of garden work that included some serious work with tools and wearing garden gloves, etc. Normally my polish would have been dead within half and hour of that, but the Sephora polish made it through. Then it lasted several more days past that. Color me impressed!
