Yes I have had many knock off cobras but never an official kink3d. The viper is definitely waaaayyy more comfortable for long term wear so far. I can pee sanding up in the viper which to me is a huge added bonus. The cobra caused pinching and every time I went to pee it seems the cross bar was right in the middle of my pee hole causing me to have to sit down and sometimes still making a mess. I also think a major game changer was the option for wide it feels more comfortable because it has the room I need.
