When using pressure-treated 2x4 lumber for edging, I usually prefer the stakes sold at the big box store alongside the 1x4 recycled plastic bender board. However, they were almost cheap each, so I decided to give these a try. My only complaint is that there is a little "give" along the 12-inch length; they are not as stiff as a wooden stake or the bender board stakes. Despite that, they are very strong. I hit them into pretty hard ground with a 4-pound hammer, and they did not break or even "mushroom" from the pounding. The pre-drilled holes are a bonus and a time saver (I always pre-drill most everything). Placing them about 4 feet apart on centers, they do a great job holding the lumber securely. I'm pleased and saved several dollars.
