I have had mine a few weeks. I love it. I bought the 1/2" one.
I read on here that there are 1/8" ones available. Don't know that first hand.
I bought mine at Joann's. got it 50% off (on sale this weekend too, 50%) plus used another coupon 20% off all purchase.
I think retail is $40. Mine is 12" (not the video's 18" )
