Could be better - Meprolight MEPRO FUBS - Self-Illuminated Folding Back-Up Rifle Sights

I have other Meprolight products and have come to appreciate the manufacturer. They have been reliable for years. I feel as if these folding back-up sights could be much better. Where the large rear sight aperture has green dots to assist you in lining up the front sight, the small rear sight aperture does not have any dots on it. The light in the front sight post was exactly what you would expect. However, the dots on the rear sight were almost invisible. The sights were very stiff when I unfolded them. I assume they would get a little easier as time goes by. For the price, I was disappointed.
