Celestron upclose - Celestron UpClose G2 20x50mm Porro Prism Binoculars

From the Optics Planet web site I purchased the Celestron UpClose G2 20x50 Porro Prism Binocular.
Code: CI-BI-UPCLOSE20X50-71258
Purchase Date: 01/02/2024
The package arrived in good condition. However when I unpacked and tried the binoculars I found them to be difficult to focus.
I discovered that while focusing, the two oculars (the lenses you look into) seemed to be moving independently, that is to say they didn't move together. I continued to use the binoculars but soon became annoyed with this focusing problem.
I usually don't return items that don't meet expectations, I disassemble them and throw the parts away.
The first item I removed was a flexible closing cover at the front of the binoculars, the point around which the binoculars rotate to accommodate the distance between the eyes. Under this cover there is a screw that holds the two oculars onto the focusing shaft. The screw was loose, had the cover not been there the screw would have fallen out. Tightening that screw to an acceptable firmness has partially solved some of the focusing problem. I would not recommend purchasing this item, in fact I would recommend that Optics Planet remove it from their catalog.
