Review title: Binocular/Zoom Monocular?
Product review: The optics seem fairly good for the price, though definite spherical and chromatic aberration apparent around the edge of the field. Works fine at the lowest power (5X), but the zoom function only works on the right lens! I'm assuming a got a defective unit -- at least I would hope so. The objective lenses are so tiny (17mm) that at the highest power (15X), the image is so dark it's hardly visible anyway. I checked the manufacturer's "Warranty Procedure" notice enclosed and it says I have to return the item at my expense and even enclose a check to them for $12.00 to cover the cost of handling! This is no way to do business -- unless, of course, you're selling crappy merchandise.
