A 4x zoom lens is practically useless. The depth of field is tiny and the image has a milky white haze. The extra light didn't help. 20x eyepiece lenses require your eyes to almost touch the lens to see the image; my eyelashes were pressed against the eyepieces, trying to see everything. However, the 2x objective with 10x eyepieces is very sharp and rich in detail. Unfortunately if I can only use 1 of the 4 settings I can't justify keeping it. I go back and begin my search again.
