Query: Charge your phone just fine, but lights are very dim

In terms of charging my phone, these cables work just fine. No issues. But if you're expecting to see cool lights in all conditions, expect to be disappointed. The *ONLY* time you can see the entire cable lit up and flickering is in a dark room, or at night. Anything resembling daylight or a well-lit room, you can't see the fiber optic light over 80% of the cable, only at the USB end. The lighting effect is quite dim except for in dark conditions. But if it's dark, then it DOES look pretty cool. The button that cycles through different lighting modes works fine. My scores explained: Durability: 4/5 . Didn't put 5 because honestly I haven't had them long enough to know how durable they are. Quality: 4/5. Seems to be put together fine, but I'm skeptical of how many times the control button can be used. So far works as advertised in terms of charging. Traveling: 4/5 The cable is 6' long so is that really convenient for traveling? Individual buyers should decide for themselves I guess. Overall: 3/5 stars because of just how very dim the lighting effect is in anything other than a dark room or at night.
