Our first 3 house we used concrete donuts. They sometimes cracked and had to be replaced.

Two years ago Amazon had Grasshole on Black Friday then Prime day sale set of 10 came to $3.95 each basically had 4 months to return. Last donuts were $5 installed (or buy $3.50 self installed) and within 3 months had to start clearing out grass, that either grew under or over.

Not only does Augustine grass have a difficult time growing inside. They have held up to landscaper equipment. Easy to trim for odd places. I used a bulb planter to install, took about 2 minutes per. So little maintenance compared to regular donuts.
