Good magnification with a large objective lens (great for low ambient light). Adjustments are a lot easier ("tuning knob") than the old style. No issues within blurring, constant adjustments, etc. Would recommend.

There’s not much you can say about the adapter. I mean it works so what else would you expect? Well, it is well constructed and makes a nice click when installing your lens. I read some of the reviews on the cheaper alternatives and saw reviews mentioning the product feels cheap and how the lens are not firmly and securely attached. I rather not risk it but others have without issues. If you’re on a budget, do look at the cheaper alternative. If you can afford it then this is the one you want.

First off, I would note that all of the negative reviews of this monocular reflect the writer's lack of knowledge of what optical specifications mean and/or the inability to use and adjust a scope for the optimum clarity. This product is exactly as described for size, weight and power. The 40mm objective lens provides for a very good image in low light. The adjustable eyepiece is convenient for eye glass wearers. I was very impressed with the quality of the scope and optics at this price level. The body has a rubberized texture and knurled surfaces on the adjustment points. It feels solid and should hold up to minor abuse. although it is a little heavy, it is about the weight you would expect for it's size. I was able to zero in and get a sharp image with little fuss. Although one can view at 30x magnification with a minimal amount of shakiness, the ability to attach a tripod is helpful for extended viewing. The monocular is easy to slip in a pocket or carry with the included lanyard. It comes with a case that has a belt loop attachment. It has lens covers although they do not have a tether attachment meaning they can be easily lost or misplaced. You can do much better for a monocular if you're willing to spend more money. At $30 for this one though, you can't go wrong. You are getting a 40mm objective lens, BAK4 prism, fully coated lenses and lots of other useful features making it an ideal scope for all kinds of activities.

I attached it on my Swarovski 85mm objective spotting scope lens. It fits very well. It seems to be able to fit even larger lenses.

Good product used 4x already ND sealed like sumerin

It's heavier than I expected but the objective lens is large and the price is very reasonable. For the money I love it.

For those looking for a front objective lens cover (which Leica should have provided!!!), the Leupold 20mm cover doesn't work. However, the Butler Creek 02 Eye Flip Open Scope Cover works excellently (1.225"). Try a couple different size rubberbands over the objective lens barrel to give it a snug fit and it won't budge, is watertight, and the rubberband can't be seen. Also it doesn't interfere with the focusing ring.

Excellent Binoculars at affordable price.Due to excellent objective lens,the Binoculars are awesome.A must buy Binoculars,excellent service from fotocart.
