This is exactly what I needed like a year ago but glad I found it now!
The light on the magnifying glass makes all the difference in the world! I've used this daily since I got it.... mostly to read labels and other teeny tiny print the manufacturers are betting you won't bother reading.
The light is a perfect amount and helps even those that can see perfectly fine, see things more clearly. For example, last night we were setting up a new TV and it's always hard to read the numbers and labels on the back of the devices. Well, I popped this baby out and let me tell you, it saved about an hour of frustration. We were actually able to watch TV together after the whole set up process - shortened due to this tool.
It takes 2 or 3 AAA batteries which is okay because I have enough USB devices at the moment. So, be prepared for that. It would be nice if the light automatically turned off after a certain amount of time. I've already left it on numerous times so probably sooner rather than later, I will need to replace the batteries. Small price to pay for being able to see things clearly that I could otherwise not. Plus, the price is very good. Get it! You won't be sorry.... And you'll find it out of your drawer, used by others quite often! So, maybe hide it!
