We used a gas engine splitter for a long time, the engine wore out so for Christmas my wife bought a DR electric splitter. This thing splits what ever I throw at it, 6 month no questions asked return, 4 year warranty. I have split about 5 cords of wood with it no problem at all, cuts time since it has on the lever a fast travel speed and then a split speed, so if you have short rounds it doesn't take forever for the ram to reach the round.
I pull logs up to the shed I store wood in with my tractor, cut them and split in the same place and stack. Most wood I use has been down for 2 years since I had the place logged.
They say the DR will do up to 16 inch diameter logs I have done way bigger.
The thing I like is if the weather is bad I can split inside the building and close the door to stay warm since there are no fumes or noise really.No gas to run out and buy, no fighting with a cold engine, just push a button and hold a lever down and they cost less than half of a gas powered splitter.
This is one purchase I am glad the wife made.
