Razor-sharp bright optics
592371
I've had these binoculars for over two months now. I'm blown away with the razor-sharp and bright optics. I got the 10x magnification and have no trouble holding them steady. In fact I tried some Canon image stabilizing binoculars (including chromatic aberration)and had more image shake. I also think the rolling-ball effect that some people mention is nonsense. The build quality is without equal. I've used Zeiss, Nikon, and Leica binoculars but these are in a class of their own. The image is sharp to the very edge and with no distortion.

Provides a much better image then I had hoped for.  Very sharp and bright regardless of magnification.  I am extremely happy with the item.

Very well made.  Provides clear, bright images and is easy to get a sharp focus over a very wide range of distances.

Ii bought this binocular because of my experience with other Swarovski optics. I needed a compact binocular but everything I looked at was just not bright enough or clear enough to bother with. After trying the compact Swarovski's I didn't hesitate to pay the rather hefty price these optics demand. The image seen through the Swarovski's is clear, sharp and bright. My only complaint is that they are made in 8x magnification. A 6x would be both adequate and appropriate for this size lens and would have been even brighter. You really can't hold steady enough with an 8x binocular to use the available magnification. I guess the bigger is better syndrome demands binoculars to be made in magnifications greater than is really useful. This is also true of my 8x50mm Swarovski binoculars as well, but the extra weight does help to dampen the unsteady image a bit more. Other than my personal feelings on magnification, I couldn't be happier with this product. I have an easy to carry high quality binocular in my pocket or butt pack when ever I go traveling, hiking or kayaking.

I've been pretty impressed with CVLIFE gear lately. This scope can zoom in far and the glow in the reticule is very bright, easy to see during the day. The scope is really long, looks about 13 inches. The red and green lighting look good and are adjustable dim to bright. Mounts are good quality too, strong metal. I really like the lens covers they include that I wasn't even expecting! The front one's a little hard to pop up but the near lens one pops up easily. Much better than covers you need to take off constantly, these are easy to open up to view. Good mid-level hunting scope. I received this product at a discount in exchange for an unbiased and fair review.

Although I have not utilized all of the features, such as adjusting the led lighting angle, I am very impressed with how well the 1 X magnification lens brings my entire computer screen and text into focus at a distance of about 3 feet. It defines the text more clearly than my progressive prescription glasses with less eye strain. The 3.5 X lens allows very close-up magnification if and when needed. I am still exploring all the features, but so far, I am very pleased this well-engineered, versatile product.

The lenses in these glasses are really good; very sharp, clear.  Great shape and coverage all around eye area; lenses has a penchant for popping out sometimes if the case is squished in my purse--but pops right back in.

This is a good high-powered eyepiece. Whether in my 10" Dobsonian (where it gives 171x mag, and true field of view ["TFOV"] of 0.35 degrees), or my 90 mm refractor (where it gives 94x mag and a TFOV of 0.63 degrees), views are crisp and clear, and the 82 degree apparent FOV gives an immersive feeling. Jupiter and its four Galilean moons look especially great in this eyepiece. Recommended - although this is not ESSENTIAL, since a Plossl eyepiece of similar focal length would be sufficient, why not upgrade to this if you can afford a few extra bucks?

Generally, I favor porro prism over roof prism designs, but the good reviews here and elsewhere, the $50 rebate and the Amazon sale price, were too much to resist.

The build quality of these 10x42 ED glass binoculars appears excellent. The focus wheel is geared 34 to one, which seemed high at first, but quickly becomes a feature. The eyecups have a good range of adjustment; one of the three detents should work for you. The range of adjustment for different pupil separations is good. I have deep-set eyes and a narrow nose and find the eyepiece cups too large or the bridge too close on some bins. The Endeavor ED is fine.

I use binoculars for night viewing of the sky, and for occasional birding. My prior pair was a 10x50 and to my surprise, the Endeavor ED has a much brighter image. Color is good, details are crisp, and color shading in shadow is seen nicely.

At night, these bins show very little chromatic aberration (color fringing) when looking at the moon. During the day, against a blue sky some green CA is perceptible. However, it compares favorably with more expensive roof prism binoculars, and is not extreme.

The bad news is that the first pair I received had a lot of CA in my opinion and a good deal of flare when looking at a ground target in the direction of the sun. The severity of the flare was just not acceptable. I called Vanguard, and Michelle and Mike, asked my some questions and Mike suggested that I return the pair for replacement under the warranty. I thanked him and decided to use Amazon's easy return process instead.

Two workdays later, I have the new bins, no flair, and noticeably reduced CA. The daytime view is just as bright and crisp. The nighttime view of the Double Cluster is a double wow.

Of course now that I was aware of it, the amount of CA in the replacement pair, continued to nag at me. It was not severe, but still visible in some targets. I have no comparable or better bins by which to judge. I posted an afocal image showing the worst CA on the binoculars forum at cloudynights.com.  Some knowledgeable binocular enthusiasts replied that CA is going to be seen on the right targets. One poster said this. "Even the Swarovski FL's show significant color fringing on a high contrast object. Your vangaurds are just fine  judged by your photo."

I am officially not going to worry about the CA. The CN folks are correct. Reviews on the birder forums speak of some CA in bins that cost 10 - 15 times what I paid for the Endeavor ED.

If you can accept some CA as a tradeoff for otherwise superb image quality, these are great bins. If you cannot accept CA you may have to look to a much higher price point.

This is a quality product at a very reasonable price. It has 2x magnification and you can use it to focus in bright sunlight. You peal and stick the metal rectangle frame to the LCD screen and the Viewfinder quickly attaches magnetically to the LCD screen. Make sure your screen is clean before you attach the frame to your LCD screen or it won't stick well.

Excellent binoculars.  Exceptionally bright and clear optics.  Easy to hold and focus.  I gave it 4 stars because the lens caps suck.  They don't stay on well and will be easily lost.

Incredibly sharp, quick focusing and solidly built!

Very clear, crisp optics!  I wanted low power binoculars with large optics for my hobbie, satellite searching at night.  My first view was of a thin crescent moon.  Craters and details popped out, and I could see a tiny (as in invisible to the naked eye) aircraft in the distance that was in the line of site. Jupiter was out, so a quick look, yes sir, I could make out the disk and I could clearly count 3 moons.  I am very impressed with the quality of the glass at the price point.  I got a tripod adapter, however, one DOES come with it so I did not need to purchase separately.  Nice ruberized surface makes gripping them easy, and they are not as heavy as I thought they would be.  You do need to steady them against something OR use the tripod adapter, otherwise there is a lot of shaking.

I bought these to replace my 10x25 binoculars for bird watching.  These are heavier at 15 oz., but the bigger lenses definitely make viewing brighter in dim light.  Everything is sharp and clear with diopter focusing.  I recommend them.

This is a very curious little binocular. The description reads "night vision". Now true night vision is either through light amplification technology, or light augmentation through infrared technology. At $15, either of these were beyond the price point of this binocular, but it looked like a good portable binocular for an emergency bag. To my surprise, they give very good light transmission in low light levels and at 30x magnification, offer an image of about the same brightness as the naked eye. If you know anything about optics, you know how impressive this is. The lens coating reflects a copper color, which I can only assume is making use of the low light spectrum of twilight. I am sure I could find fault with color correction if I tried them at different light temperatures, but they work well for what they were intended to do. This is all a person can ask for the $15 expense.

A very fine optic, but I needed magnification because of failing eyesight
