5 of 5 GREAT July 29, 2021
Reviewer: MMmmFlower from Falls Church, VA United States  
Not exact original, but overall "Great"!  I'm still in the works ast to what I'm planning to use it for, given the fact that at the time of purchase I only bought one.  I do plan to make additional purchases in the future...

1 of 5 Doa July 26, 2021
Reviewer: Joshua Lloyd from POTTSTOWN, PA United States  
Bought the NPB4 for backpacking trips. I was super excited to jump on board because all the previous models had very high reviews. Mine however came DOA. Looking very much forward to getting a refund.
