Your right it is by far the most popular CPU Cooler even when excluding the Hyper 212 Plus sale( 212 Plus uses same heatsink i am sure) ...
For $25 not a bad deal. Since I paid more i am bitter, so take some of my comments about it with a grain of Salt. though if I was going to keep using it I would get a Corsair SP120 or a noctua NF-F12 to replace the fan that comes with it. But I must say that the improvement over the Intel Stock Fan significant enough to get one.
