    I did the video "Birdwatchers Rejoice!" and this review goes with it
  

*by M***S on Reviewed in the United States on August 29, 2018*

I bought a hummingbird feeder and these binoculars thinking I would get to catch a peep at the hummingbirds feeding. I thought the cell phone attachment may be some kind of gimmick, but I'm happily surprised. First, there aren't any instructions on the cellphone attachment, but if you take a look at it, you can figure it out. The clamp holds your cellphone. The piece that looks like a magnifying glass without a lens goes over your camera lens. The binocular cover with a hole in the center goes over the part of the binoculars you look through. Hold the cellphone at a 45 degree angle, slider it over the cover so the magnifying glass thing mates up with the hole in the cover. Move it down straight and your cellphone is now attached so you can shoot video or take pictures.The coating on the lens works really well in low light and you get really good focus. I thought my cell phone's autofocus might clash with the binocular focus, but it didn't. I didn't have to change anything on the cellphone. I could use the focus on the binoculars and look at the cell phone screen to see what I was aiming at, if it was in focus, etc.These binoculars are hefty, sturdy and I will definitely be able to take some amazing shots and video of the hummingbirds with this. It's a well made product that is built to last

    Great for the price, comes with a nice case, tripod stand, can't be beat.
  

*by R***M on Reviewed in the United States on June 5, 2018*

I bought these primarily for birding. The birds are returning here in the spring and it is wonderful to watch them from afar. These adjust very easily for your eyes. I wear glasses and contact lenses and no problems whatsoever. I even was able to use them without glasses by adjusting and they work fine. The case and tripod stand included is a very nice touch. This way when looking at far away objects you can have the binoculars steady on a tripod. Really nice touch. Definitely recommend!
