TruGlo TFK Pro Fiber Optic Sight

Was very excited to have these purchased for me a gift. As I had wanted to upgrade my factory sights. Package arrived undamaged and in good shape. After removing the sights from the Package and reading the manufacturer info contained there in. Before having them installed on my firearm I went into a dimly lighted room to test the brightness of the night sight portion of these sights. Totally dissatisfied! They did not glow. I held the sight at arms length to simulate being installed on my firearm. And could not see the dots. I held them up to my eyes and could barely see a very dim glow. I had another member of my family try and they had the same result. I then went into a dark room. And again could not see the sights. In the daylight or very well lighted room the fiber optic took over and we're ok. But not as bright as I had expected or hoped. I tried to contact Amazon to return them to find out, this item cannot be returned. Have contacted TruGlo twice via their Contact us form. With no reply. Also now have contacted them directly via phone and submitted pictures, proof of purchase etc etc after asking them about the sights and could they please identify an age for me. As the sights per the documents included in the package state the glow portion sights are good for 12 years. I have suspicion these may be 1/2 life or older. Still waiting on response from TruGlo. If none soon received will contact Amazon and request action on their part. Do not recommend!
