I am currently using the Nikon Aculon A211 10x50 binoculars on a tripod for nature and stargazing. I was looking for a cheap way to make this connection with my Samsung S9+. This adapter works perfectly. Other reviews say you can't carry your phone in a pocket and then use this adapter, but that's not the case. While it's best to keep the phone out of a case, it still works great with a slight zoom from the camera. I have my S9+ in a life proof case and have had no issues. However, if you are serious and want to get the best results, take your phone out of the case.
