Question: How much do these binoculars weigh?
Document: I also bought  OPMOD 8*42 binoculars and the OPs are much better! What more can I say. How about buy the OPMODsand not the Zhumells.
I bought these for my brother, who is a hunter, for Christmas. His hunting buddies were floored when they found out the price for these binoculars, and said they were as good, or better than their much higher priced binos. If you do a search you will see mainly high reviews, they are all true.
This is a nice pair of binoculars to watch birds at our feeders. They are easy to adjust and are comfortable.
great value for the $$$$. i recomend this item for anyone interested in a good pair of binoculars. look and see.
So my "fancy" Zhumell binoculars will stay at home as a back up, while my "cheap" Bushnells will continue to accompany me out in the field.
I am thrilled with the binoculars.Live in Sarasota with a pond in the back, and can see the color of the bird's eyes. Well, almost.Thanks again.
These binoculars are compact enough to take anywhere. Once you gt them adjusted for your own eyes, they do a great job of bringing things up close! The optics are good.
These binoculars are wonderful! I am a beginning birder and while there may be better ones out there, for the price, they are great! Sharp, crystal clear image that is easy to focus. I recommend them!
The clarity is amazing. I use this product every time I'm at the beach. I have seen unbelievable sea life up close and personal thanks to these binoculars  ....Awesome!
I bought the Binoculars for my wife because she is a bird watcher and she has eyes that are very close together . Sorry to say that these were not close enough ether. But I used them and only could say wow ! I now own them and can not say enough good about them. Works perfect . Good product Zhumell. Thanks
Answer: Mine weigh 20.65 ounces.  These are great binoculars.
