Review on Security Computer Rearview Personal Rectangle by Matthew Wheeler

I bought this to look after my disabled wife while I work behind her at my desk. We have light in our room, but I can hardly see her in this mirror. Also, the "convex" curve is very thin, so I have to constantly redirect it as it changes position on the couch. I was also disappointed with the plastic version of the adjusting nut. I was able to fix it with tape, but be aware that this is a delicate item and difficult to aim/position, especially if you don't have a fleshy object to attach it to. I ended up putting tape on the monitor where it attaches so I have something to hold on to. If you need a wide-angle mirror for darkroom use, keep looking.
