Thanks for watching the video. My product is made differently, both in the materials used to make it but also in the method that one uses to install it. The shape also plays an important role in its performance long term.
It has a 7" diameter same as the concrete donuts. I haven't personally seen a sprinkler head it wouldn't work on but I'm sure their are some antiques out there somewhere. I do have a 30 day return policy if they shouldn't work for any of my customers. Thank you again for your comment!
