I, too, have a PowR'Kraft 7-ton splitter. I haven't had a problem with it and it has split virtually everything I have tried to split (note that it is somewhat self-limiting, in that I can only split rounds that I can manage to heave up onto this horizontal splitter). I start in "fast" (4-ton) mode and move to "slow" (7-ton) if I notice any resistance from the round. I split mostly locust, maple, oak, and hickory. I have strapped mine to a hand truck also, since I need to wheel it across rocky terrain. I think the wheels on it would work fine on pavement, but that isn't always available. The only other word of advice I'd give is to be sure you have a 20-amp breaker and use the shortest 10-gauge extension cord possible, in order to avoid a voltage drop, which will cause loss of power, overheating, and possible motor damage (which is true for any electrical appliance, if the extension cord isn't sturdy enough). I highly recommend this splitter, for those who are considering an electric. It's quiet and there's no messing with gasoline, oil, filters, and exhaust fumes.
