Rated 2.0 out of 5.0 by MaxR this knockout version is a pain
This flange has a stainless steel ring that is much better than a standard painted steel ring.
However, this particular flange is really only necessary for new construction when it is being installed on the rough rather than the finish portion of the job. The test plug/knockout plug is more of a pain to remove than it is worth. It also doesn't leave a clean edge when it is punched out of the flange. It always leaves uneven and jagged pieces of plastic on the perimeter edge where the plug used to be. This can be smoothed out with a Dremel and a sanding wheel but that shouldn't even be necessary if this was designed a bit better.
Unfortunately, Home Depot doesn't sell the regular version without the knockout plug so this is your only choice from them.

Rated 5.0 out of 5.0 by CodeMonkey1313 Works Great - Just Read the Instructions
The instructions aren't very clear, but after reviewing the comments on this site, as well as the video on the manufacturer's site, I decided to give it a go. I put the flange on the floor (not installed since i didn't need the cap at the time), and hit the rim of the cap with a hammer, not too hard, and just rotated it around and noticed it was starting to sink in place. In theory this is the part where you'd grab the edge with pliers, but since I didn't want to mess with digging channel locks out of my tool box I used the pliers nearest me and tapped the cap from the other side and it popped right out. No messy edges, no problems.

Rated 2.0 out of 5.0 by MTMT It is really hard to knock open
Watch the video that Sioux Chief puts out at their website. The ring is really hard to knock out just like the other reviewers said and like the website video. Like one reviewer said, take it to your bench and remove it there. If your worried about sewer gas and such, stuff some paper, rags or plastic bags in the hole.
I was doing a repair and I started getting concerned about how hard I was hitting and it wasn't cracking like it was suppose to. Any harder and I was worried about the possibility of cracking the tile around it. And then oops, I hit the center and the center fell into the drain. I ended up starting a crack with the small hole and the plyiers. It was torture all the way around.
Good idea but they need to cast the par with a thinner break away section.

Rated 5.0 out of 5.0 by Aluck Works Great, one tip
After reading the reviews I was not sure about this item. Here is the tip I will give you... BEFORE you install the flange take it to a hard surface, put a towel on the ground set it on the towel (to protect the bottom) and bang it there. You will see the "cover" move down and crack from underneath. At that point you can get a vice grip and pull it off. I did it this way because I was afraid to hit it as hard as the reviewers below had stated once it was mounted.
This was purchased because our old flange had broken twice and I fixed it with a steel repair. The item itself it great. It is steel so no more cracking of the flange

Rated 3.0 out of 5.0 by Lasrocas Needs instructions
This is actually a really easy product to install. I am very happy with it. The other reviewers complained that no instructions came with it to remove the knockout cap. I was at a loss until I read, from the reviews, how to do it. You really have to hammer all around the raised edge of the cap about 20 times, with a medium blow. It then sinks a bit, and you can just pry it out with a screwdriver. The scary thing is that you have to hit it hard enough that you might think you will damage it. I only give it three stars due to the lack of instructions. They should at least put a diagram on the sticker of hitting it with a hammer in the right place to remove the knockout.

Rated 4.0 out of 5.0 by DGPaul Solved a major problem for me!
Our toilet has had a wobble for a while. Removing it, I discovered the flange was too high. This made what could have been a nightmare an easy fix. It allowed me to cut away the old flange and install this capping the existing pipe.
I have to agree with the reviewers who complain about the knockout: it takes a lot of force to get it to separate for you to finish with the pliers. I am glad I read these posts and was prepared for it to take some time and force.

Absolutely ridiculous. I grasp the idea behind this product, but it's not worth the effort. JayG had it right in his review. The 'easy knock out' plate is exactly the opposite. We tried everything before finally just taking the hammer to the middle of it and bashing it through. Again, as the previous poster said, the resulting plastic shards make it so that it nearly impossible to use. Find something else, anything but this.
