I've got the splitter and assembled it, but have only "test drove" is on a few pieces of seasoned wood I had lying around. This thing is a BEAST. There is an assembly video on-line that covers the 25 & 28 ton models. Assembly is more-or-less the same for the 35 ton as well, but Jiminy Cricket is the beam assembly heavy! I tried to get it out of the shipping crate and standing upright with just my wife's help (she's a trooper), but it almost went badly. It's really too heavy for two people to do IMO. I wound up using my tractor to hoist it up. You also need to pay attention to how the beam is hoisted in relation to the hydraulic hoses, or you'll cause yourself some issue getting it properly oriented. I'm going to start chain sawing up my big wood in the next few days and will give a more detailed report.
I have looked at the machines they sell at the big box stores, and can safely say that for the money, this thing is a much better value. I did notice Tractor Supply had some units out front the other day, but I'd already ordered the YardMax, and have no regrets (thus far, knock on weed, pun intended)
