I've used a American Angler Saltwater version for about 15yrs.. A few years back I was filleting 74 tilapia in the 3-5lb range and a friend, whose dock I was cleaning them on, had a Mr. Twister. I would use one until it got a little hot to hold and then switch to the other one, this was a steady paced ordeal with no problems out of either one. Both of these were 110v corded models, I can't speak for the rechargeables as I haven't used them. This is an important topic with some fine feedback from members, thanks for posting it.
