the two little fishes one and the kent one are both poor products with cheap plastic and o-rings that rarely fit properly. I used to own the two little fishes one and now own the kent one. It works though but I had salt creep leaks on both. The KENT one resealed all of the potential leak areas and it works great now. I suggest doing the same if you get either just to be safe. Much easier to seal them before use versus waiting to find out if you will get a problem and then having to tear it down.
