The Rapala cordless came in yesterday. Needless to say it went right back. The trigger was uncomfortable, it wasn't balanced very well, and the blade oscillation was noticeably slower than a 110v knife.
I have the cordless lithium model, and it did well initially. I have filleted up to 10 2-8# blues at once. Then it got where you had to hold it just right for the trigger to work, and now needs to be taken apart, and fixed if ever used again.
