Since the days of the GameBoy, I have never been a real fan of screen magnifiers. I admit they are a cool thing, but I never thought they magnified the screen enough to make a big difference. This is was also the case with the lens on the
Flip-n-Light. The more I played with the lens, the less and less I liked it. Whenever I would try to use the device in a room with any external light, I would either run into the problem of light glare on the lens, or a nasty shadow (from the len's frame) appearing on the screen. Turning the light on helped to negate some of the problems, but I found it easier not to use the device.
Despite what the back of the box says, the light still gives off glare. If this were the only problem, I wouldn't complain. However, the magnifying lens reflects the glare, giving you three or four different 'white spots' on the screen instead of one. In addition, the light does not seem to illuminate the screen enough. For once, I wish a company would put lights on the sides so the entire screen gets light and not just the top half.
That said, the Flip-n-Light is a decent choice, but it's not the answer most GBA owners have been looking for. If you still haven't found a light you like, it is probably worth a look. But if you have a light, there's really no reason to try this one out.
