They're kiiiinda awesome...if you get the right kind.
Before investing in a pricey pack, start with something a little more affordable, like these strips from Ardell. If you like long, fluttery, but still realistic-looking lashes, these babies are it. Just place the upper strip on top of your lashes, and line up the bottom strip underneath your lashes (like a sandwich) until the magnets click together. Easy. The biggest complaint about magnetic strip lashes is that the ends have a tendency to lift. The fix: Cut the strip in half so you can customize the shape to fit your eyes.
