## Most critical reviews (3 lowest-rated)

### 1/5 — Not Good

*2023-07-19, version 1.4.3*

Does not even come close to PyMol or any other molecular viewer

### 1/5 — Structures are all reversed

*2022-02-03, version 1.2.2*

This is a nice little molecular viewer that I thought I might use in my biology class  (I’m a Bio professor), BUT when I opened my first structure from the protein database - 2cv5 (DNA wrapped around a nucleosome) - the wrap of the DNA around the nucleosome core is spiraling the wrong way and the DNA itself is winding backwards. The viewer is giving incorrect mirror views of the structure. This can be seen by comparing the app view with the view at RCSB itself using their 3D viewer in the browser or in PyMol (a more professional structure viewer). I tried other nucleosome structures - the same error. 

I am led to conclude that all proteins are shown in mirror image of reality. As such this viewer should not be used until this issue is fixed.

### 4/5 — CAN DO NOTHING

*2023-12-28, version 1.4.3*

Just a pbd viewer
Elegant
But CAN DO NOTHING
