Finally got round to getting this and have been very pleased. Good quality (as always with strength shop), nice and sturdy. I bought an additional handle for it as I only have limited room to push before I have to go back the other way.
Size is just right for me, it sits nicely on top of my plyo box in the garage so out of the way when not it use. Can't comment on the height of the handles compared to a full sized sled as have only used drag sleds before.
I do find the handles move inwards slightly after pushing so I have to hoik them back straight to unload the plates. Have tightened bolts, perhaps some loctite would help here, or might fashion a brace to sit low between both handles. Very minor inconvenience so I probably won't bother truth be told.
