This was a great tool to see far away ONLY. We were near the mountains, so it was great. There was only a focus option and NO zoom in or out function, as EVERYTHING was up close. But for the money, it was great!

I’m a bird watcher and needed a pair of binoculars but didn’t want to spend too much. I am extremely pleased with these! The crispness of the picture quality is excellent! If I had tried them before buying I would have guessed they cost over 100 bucks easy. I’m a Freedeer fan for life now!

I was packing up got my son’s regatta and could not find my regular binoculars, so I jumped on Amazon to look for some. I decided on these because the specs were what I needed. They arrived the day we were leaving. When I got to the regatta, I brought them out, and was amazed by the clear clarity and magnification of these. For a last minute purchase, they were great. Sometimes you don’t have to buy “brand” to get quality. I would highly recommend these for starter binoculars, then if you want, work your way up to the expensive ones.

I want to like this thing, but it just doesn't work for me.The problem is that the fingers that hold onto the optical deviceare just too short to hold on securely enough to trust it with my phone.Keeps falling off.

Great device but the telescope adapter ring should be a bit deeper to handle monocular with extendable hoods. The short depth does not get enough friction on the more flexible rubber when the hoods are rolled back.

advertised to work to view on binoculars or even scopes. you cant see anything and when you do try to zoom in it terrible. tried it out the day i received with my iphone SE and a iphone 8 on my binoculars and a scope and the following Monday tried to return it and it says not eligible for return. this was a prime shipping purchase. very disappointing. If that would have been listed anywhere visible i would not have purchased. Prime shipping has always been up till today free returns.

Almost impossible to use without 3 hands. It's difficult to line up the camera with the view finder but even when you finally get it perfect, the whole thing falls off once you raise the binoculars up to look at something. It's just too unstable and does not fit a standard rubber eyepiece securely.

I like the simplicity of the product. It's relatively easy to use. I think the "claws" that hold the phone could be a little deeper, and I feel the adapter "cup" could be a little deeper as well to better grab the eyepiece of your binoculars or spotting scope etc. It is perfectly functional the way it is and a great value compared to some branded products that sell for almost 10x the price.

Pretty poor grip. Needs to be tight so as not to fall off but then when you tighten enough the jaws jump out of their track and it suddenly fails totally.Add to this the cheap plastic construction and I'd say it was just "ok" but cannot be bothered to return it.

It is always a gamble when you buy something that is so cheap....these are a true bargain. Easy to use and great light quality. Not overly heavy and 2 metre focus....I have tried bins which are over £100 and these were better. Kept in the vehicle ready for use.

Found fixing to phone difficult,not yet taken rubber eye piece off binocular to see if it fits

easy to use, used it on microscopes as well as my telescope.

Impossible to use as it covers the power off switch
