This thing is amazing. I purchased it thinking it would be a gimmick item and not work. I was pleasantly surprised - this thing rocks! I've used it to split over 30 logs since purchasing as my wood supplier did not cut the logs as I wanted this year. It won't replace my splitting axe for the big stuff, but otherwise, this makes my life much easier. I haven't mounted it to anything yet, though will to some heavy 2x12 base to give some more stability, but this thing is great. I suggest using a sledgehammer versus handheld to make sure you can really get some power going. This is the best thing I'd recommend this year if you are splitting a lot of wood.
