## Customer Reviews

### ⭐⭐⭐⭐ 







  
  
    Not bad. Just not for me.
  

*by H***H on Reviewed in the United States on August 21, 2020*

My only issue with the bag was that the opening for the main pocket only opens half way. I initially liked this design. However, it rendered the pocket on the main pocket "door" unsusable for my purposes. I intended to keep a small (6"x7") drawing tablet in this pocket but it got in the way of fully opening the main pocket.The feel of the quality of the material is not great but on par with other bags in the same price range.I bought four bags from different brands to compare.

### ⭐⭐⭐⭐ 







  
  
    Good, but could better with just a few additions
  

*by N***C on Reviewed in the United States on January 18, 2020*

I like the compact nature of the backpack but missing some key features.  Is it THAT hard to make a key ring holder? Or a slot in the straps for transit cards? Or a anti-theft zippered secret pouch in the back? Or a single strap to be used as a shoulder bag?  Also if you make the strap stow away area accessible, it can be used for extra space, like placing a thin rain/wind breaker.  I would pay a bit more if there was a zippered expansion feature that doubles the interior volume, so that I can use it as a weekender.

### ⭐⭐⭐⭐⭐ 







  
  
    Easy to use
  

*by J***R on Reviewed in the United States on November 8, 2019*

I have used this backpack while working for months now. It’s amazing! The charging feature works well, even though this bag has been through heavy rainstorms, dropped, kicked, thrown. It doesn’t have a scratch on it!! Wipe clean. If you need to freshen it up a bit, fabreeze works well. I like to switch back and forth from backpack to briefcase depending on whether I’m dressed business casual or business professional. I’ve received many compliments on it.
