Mine didn't come with it either. I took it back to Verizon and said "Hey, this didn't come with Teeter. I want a refund."
The customer service rep quickly pointed at me, announced to the entire store that I didn't like my Rezound because it didn't have Teeter, and they all laughed at me.
So I left without Teeter. I was sad.
I decided to go visit my grandfather, who was drinking Wild Turkey down at the American Legion all day. I asked if I could borrow the keys to the Sherman, which was parked out on the lawn out front. No problem. Drove back to Verizon and ran over everyone with my Sherman.
"That's for Teeter" I remarked as I spat on the smooshed bodies of those who laughed at me. I still carry my Eris to this day just to play it. I love Teeter.
