Query: Easy to use on medium hard clay yard like mine in Texas.

There are so many reviews that claimed this yard tool will compact the soil, but I went ahead buying this for my yard. I calculated the if I use it with a little modification of stroke against the advice of the manufacturer, I will make a large hole in the ground almost equivalent to the exposed area of the other model with cylindrical holes. What I do is to jam this on the ground and then push the handle forward and backward before I pull it up to start another holes. The only portion of the holes that are compacted were the ends of strokes, the forward end and the backward end, while the two side of each hole have very little compaction. What I like is to collect the irrigation water into the ground, and not so much of aerating the soil in my yard. It worked so well for my front yard that is slopping toward the street like almost all homes in our neighborhood.
