Excellent tool for it's price!
Used it on D40 & D5000 -
viewfinder picture is clear and sharp and appears much bigger
easy to attach
DK-21M extends a bit making camera handling a bit easier
definetely recommended, price is ok as well

Worth it for me
Just bought it today and was installed in-store on my D7100. I immediately noticed I could actually now see the info at the bottom of the viewfinder instead of just blurs. Also helps keep my face from smearing up the big lcd screen. Two birds down with one new eyepiece. As much as I like it, $30 is still $30. Half that would have been better. It's staying on my camera full time.
Easy to install. Does what it says.

PROS: Bigger image. You can read the data in the viewfinder on baseline
CONS: Little eyepiece glass so you need to put your eye very close. Poor eyepiece ergonomic design, it can be fall out.

It also fits the D5100
I just put this eyepiece on my D5100, and though it does not make a huge difference, it is significant enough to make it well worth the few dollars it costs, and a very welcome upgrade to my D5100. It really helps to focus on long zoom shots. It stands about 1/4 inch further back than the rubber eyepiece that comes on the camera, which is also better; it gets your face off of the monitor screen. And in contrast to what I've read on some reviews from other websites, it does not take away from the area of view of the viewfinder; at least not on the D5100. I can easily see the entire rectangle, and what's inside it, better than without it. It is now a permanent part of my D5100; I will never take it off!!!
