變色龍4X是次級片, 這個可信性較高. 外國也有討論太誘Valueline系列是以4X來賣卻混入了4X, 8X或16X碟芯的片子.
分辨Valueline的方法:
Take one more look at the stamped serial in the clear plastic center of the hub ring and see if it has been stamped over a second time.

Its very hard to read the clear center. I part i think says EK5 and then opposite that on other side of clear hub a bunch of numbers 9k525A401819GK and stamped on TOP of that is EK5. Also on the actual purple part of the disc opposite the #s i gave u in my last post it say 0211

至於變色龍8X, 燒過300張以上8X+R, 12X和8X燒的品質也很好.
