After cutting the lawn a few times with this I've noticed that it is different and similar to the Toro Atomic blades. The similarity is that when mulching tall grass it will clog up, bog down and spit chunks; the solution I found is to mow about 6 feet, pop the front up to spray out some mulch and pull back about 1 foot then repeat (frequency depends on mower and height of grass). Of course cutting more frequently eliminates or reduces the need to pop the front end up. The difference, and this is a big one, is that this blade not only cuts the grass but does a great job shredding it, looking at the mulch you can see that the individual blades of grass are stringy and broken apart not just cut off; I attribute this to a better fin design on the trailing edge, not only are there more than the Atomic but they're also twisted to provide extra edges that break up the grass. This blade does what I was expecting the Toro to do and at a slightly better price. It also seems to bag better too, probably because the grass is being broken down more and compacts better. Will definitely buy another when the time comes.
