I had Ford OEM rails for a Ford Explorer, and I would say these rails are superior because they use metal attach end caps/connections, where Ford has plastic (get brittle in Arizona sun) end connectors. He is 14 months old and wears the 24 month size (he is in the 99% for his size). This microphone has so many features and is also plug and play. So much for that idea. Im a worship leader for our praise team at church. I am quiet happy to be the first reviewer from India for this product. Various styles may therefore be similarly marked but be of very different sizing; mistakes were previously made. I am not sure what codecs are used, but the lag was just a tiny bit noticeable while gaming if you are paying attention, and video playback was fine. It is really nice that they are attached. I looked many places for dark brown towels and they were much more expensive than these for similar quality.
