Carson MicroPen LED Lighted 24x-53x Magnification Microscope Pen (MP-300), Black

It's not very powerful, but extremely easy to use microscope. I had a lot of fun with my kids using this thing - checking pixel structure of cell phone screen, etc.

light is so dull you can't see anything. this thing is useless.

It’s the size of a ball point pen. Probably says that in the description and I blew past that. Functionally it’s awesome! Extremely sharp magnification

This is just so amazing! We got it for our 11 yr. old son for Christmas. You can see every part of a hair shaft, take it anywhere and view everything that normally wouldn't fit under a traditional microscope. However, it IS the size of a regular pen, and he lost it within a few weeks. So be very careful and keep it in a safe spot!

Battery came dead so can't even use it.

Good little scope just wished it took a triple AAA instead of the button cell, overall good product.!!

This is a neat little scope. It fits right into.... well almost anything you want while traveling around. Optically though it's a little tricky to find and keep focus on your subject you're trying to look at. The construction is also something to watch out for. It was in a padded pocket of my backpack, and while shuffling around in there the case started to split in 2. The optics still work, but I can't seem to get the case to fit tightly back together.I decided to buy the Carson Microbright Plus handheld scope for a few dollars more and I cannot be happier with that purchase. That little pocket scope is easy to use, portable and delivers a crisp image. Working outdoors in the mountains full time - I bring that scope everywhere with me. This MicroPen sadly I usually leave at home.

I am electronic engineer and I work in the repair of equipment. This a great tool, it is very versatile because of its small size. I recommend it for the workshop and tool wear in briefcase.
