    use these money for something else
  

*by M***. on Reviewed in the United States on November 2, 2019*

it's a 5 dollars items sell at 20. the smartphone plastic holder is very poor quality. the tripod is the same i had from a camera bought 15 years ago ( really). now, for 20 dollars we cannot expect something good. my fault.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Good scope for the money

### ⭐⭐⭐⭐ 4.0 out of 5 stars







  
  
    For the price, works pretty well
  

*by A***H on Reviewed in the United States on May 26, 2019*

Compared to binoculars that I have gotten around this price range, it seems to have a bit more zoom. It works well as a monocular and I would say it is perfect for things like bird watching or sporting events.I have uploaded pictures with and without using it attached to my phone. Note the vignette (outer ring of blueish black) and slight chromatic aberration (red and blue edges of objects). The focus of nearby objects is not as crisp as I would have hoped. The whole phone mount kit is difficult to set up in a hurry, but if you get some time and stable ground you can snap a pic and crop out the vignette. Be careful as the plastic mount seems flimsy for using long-term.All in all, for $28 (at the time of reviewing) this thing is definitely a capable little zoom lens. Do not expect professional photography out of it, but definitely nice for seeing something far away or snapping a quick pic without getting a $400+ professional lens.
