This model is lightweight, and it's outer coating (possibly rubberized?) has a pleasing feel. Eye relief is good, but somewhat difficult to use when wearing sunglasses. The optics are fairly sharp given the price, and it focuses very quickly. There is some distortion around the edges, but not enough to distract from viewing. Light gathering is about what you could expect - good for daylight, not good for dusk or dawn. This is to be expected given it's small objective lens. As already mentioned, the pouch is rather flimsy, so get something a bit nicer if you plan to carry on your belt. The only "con", and it's a slight one, is that the focusing barrel is a bit stiff, and since it takes so little movement to greatly change the focus, you can easily overshoot the setting you need. IOW, it's a bit touchy, but you will get used to it in a short period of time. All in all, it's not the best monocular by far, but it provides a greater amount of performance for the money than ...

Pretty much all the rest of the reviews have already said what I was going to!! This is great, handy little gadget to have around, and since it's so small you can easily take it with you anywhere. I carry it in my purse or my pocket when taking a walk in the woods so I'm always prepared if I should see a rare bird (or something else)! The images are extremely crisp and bright-- surprisingly so considering the meager price of this instrument! Highly recommended for anyone who just likes to survey their world!

High quality bright view for a low price: Use this where expensive optics might be at risk of damage or loss. Some leakage of tube grease on the inside diameter of the lens barrel forward of the objective lens (not inside the lens) Clean it carefully and you have a bright, contrasty and well-resolved image for a great price. I'd recommend using the flimsy nylon belt pouch it comes with as a case but not as a carrier. -Use the lanyard as the small size makes this easy to drop. Its size is both a pro & a con. - Good eye relief for eyeglass wearers- -Mine broke after extreme abuse (a seven-foot fall to a ceramic floor) on a sea cruise. The prism came loose) No good optic will survive this degree of abuse, but for the price one doesn't cry too much.

I own three monoculars: a 6x18 Audubon, a Brunton 7X18 Echo Pocket Scope, and a Zeiss 5x10 Miniquick. One would expect the Zeiss at four times the price of the other two to be the best, but such is not the case.The Audobon is the smallest and gives the clearest image. I have had 13 people compare the three monoculars. One chose the Brunton and the other 12 chose the Audubon as the clearest and easiest to use. I took all three on a recent trip to Italy and found the Audubon to be the most satisfactory for looking at cathedral ceilings, wall paintings and birds.

Amazing! Close Focus 13-inches!, Light/small, good optics, good depth of field, 1/2 turn to go from infinity to 13-inches. Anybody who hikes NEEDS this instrument. Provides easy trail side insect eye view of flowers and plants, crystal structure of rocks, lichens. Just an amazing tool. I've bought 9 so far as presents for nieces and nephews, friends and family. At ~$25 a great value. Absolutely amazing!
