    • Pretty good.
This is the first Chelsea filter I've owned so I don't have anything to really compare it to. Overall, I really like this and have been using it to test some gems in my collection. The only thing that is frustrating for me personally is that if you try to look through it in the same way you would a loupe it is very blurry. I have to hold it at a distance (about 4 to 6 inches away from my eye) to see the gem clearly, but then I wonder if I am seeing the color of the gem through the lens properly since it is relatively far away. But like I said, this is the first one I've owned so I'm not sure if they are all blurry up close. Still happy I got it and am having fun using it! ... show more

If you know how to use it. I is a great tool to have in your tool box. Caution! If you do not know how to use it, do not buy it. It will get you into more trouble than it is worth.
