Favorite D7000 Accessory is____?

I just wanted to throw out a fun question to everyone, asking each of you what's your favorite/must have accessory for the D7000? (besides lenses and batteries, of course ) What say you?

My Satechi Wireless Remote. I use it every day.

May I interject, "Circular Polarizer" even though I'm using a D7100?

SD card.

My Nikon grip. It makes my D7000 feel much better in my hands.
I also like my RF remote I got from Amazon.

Love the responses. Keep them coming.

Ape Case camera strap.
