While we haven't tried the gadget long enough to see a noticeable difference around the eye area (the brand tells us it takes about 10 weeks to see visible results), we did notice that immediately after using it, we looked impressively well-rested — as in, enough to hide the fact that we stayed up until 1 am catching up on Girls. That alone makes it worth buying, but we won't judge you too hard if you just want it for the Insta.
