Review on Binoteck 12x42 Bird-Watching Binoculars for Adults - Compact HD Vision Binoculars for Travel, Hunting, Concerts, Opera, Sports - BAK4 Prism, FMC Lens - Includes Phone Mount, Strap, Carrying Bag by Melissa Merkel

I was impressed with the clarity of these binoculars when they arrived. I sit and look out over the bay and I can see everything very clearly on the other side about 2 miles away. Adjustments are smooth and it's easy to get a clear picture. I didn't really try to take a picture with the phone attachment but I attached it and my Samsung S7 lined up perfectly. Can't comment on durability as I've just received them but they appear to be durable and with lens caps on top and bottom they should hold up to normal use.
