Only other fish I keep are generally walleyes and catfish which are both easy to fillet.
With this you have to first fillet them with your knife, then plug in this Skinzit and do the ribs/skin. Then you have two knives/contraptions to wash instead of one and takes more time.
Just my thoughts.
Also, you need to keep the metal wheel completely clean. If you start getting fish junk built up in the grooves, its effectiveness goes away as well. After 8-10 fish it gets scales, and other fish by-products built up on it and you have to clean it off.
IF you have one and are having problems with it, you must go slow when you are doing the skin removal step. You must watch underneath and let go of the trigger just right other wise it will suck your skinned fillet back through the wheel, and since it does not have a reverse function, you are pretty much screwed if this happens and the fillet is lost.
Right now, School is still out on weather we return it or not. As of now, I am not impressed with it. To be honest the other night I was wanting to kick Ted Takasaki in the sack because I was so pissed at the thing. LOL
