Maxi-Rod 3/16'' Launch Pad Rod

What is the point of buying a launching pad for 20-30 dollars when you can just buy this and stick it in the ground and it works just as well?

I bought one of these to replace my rod from my childhood, and the threaded joint was quite weak and it ultimately bent. I went to my local hardware store, Lowe's, and purchased three rods of difference sizes for less. The only downside is that they are not plates with stainless steel so they require care and oiling plus I had to sand them. But it saved money and aggravation.
