Used for school project!
Bought these for my middle school science class to make their own telescopes. Was a really fun lab and they worked great!

Great Clarity
I got these for a personal project. I needed to modify the focus of a laser. The clarity and quality on these was great.

Believe it or not, I use these for wood burning from the sun. Learned this trick in Girl Scouts LOL

Very helpful in different ways
I got the double concave to use with art, to check my accuracy in likenesses for portraits. The double concave ends up giving you a virtual image, as if you are looking at your drawing in the mirror, except it's not reversed. Don't ask me how it works, but it lets you see what's "off" more easily. I also bought the double convex just because it was included, but I have already used it several times to magnify small print, or zoom in on a drawing reference detail. Don't know why, but I find it much more enjoyable to use than a magnifying glass -- maybe because there's no distracting handle or frame. Very nice purchase. Glad I got both.

Focal lengths are not as advertised
Like the title says, focal lengths are not as advertised: they're 200, 300, and 500, not 20, 30, and 50.
User
Very low power, but very clear.
20, 30 and 50 CENTIMETERS power, not millimeters. VERY little magnification. My mistake.They are thin, but very clear.
User
inexpensive but good
not the greatest lenses, but good for what I'm doing.
