Review on Celestron 44347 TetraView Digital Microscope by Kevin Pirlet

Excellent in the field. (Optional battery operated). It does its job well, has digital memory, but there is a problem when viewed on a computer monitor. It's grainy. The advantages are that it is easy to use. Minus 5 achromatic - lenses 4x, 10x, 20x, 40x, 60x aren't as powerful as I need so I ordered a 100x lens hoping it would work. However, performance is application driven. It's durable and portable. It is helpful to see if there are germs in my compost tea. That's a big deal since you can't see germs with the naked eye. It's a great entry-level microscope, but I wish Celestron had made a "big brother" with higher magnification and monitor resolution. I would buy that.
