Question: It is curious that one one the more significant achievements of "Pastor" Charles Taze Russell is omitted above. That fact is that he was the primary founder of the Watchtower Bible and Tract Society, and the religion now known as "Jehovah's Witnesses." No small amount of his theology is controversial in the body of the Church as a whole, as it would be (for different reasons, perhaps) amongst Jehovah's Witnesses.

Answer: Negative


Question: I think this is my first review in the years I've been on Amazon, but for once I feel that I need to speak out on a bad product.I bought both the DGK and theWhiBal White Balance Reference Card - Pocket Kit (2"x3.5")and I have to say that the WhiBal just feels better and feels that it will last a lot longer(the DGK cards are only about the third of the thickness of a WhiBal). However the Digital Grey Kard has one thing going for it, it has a superior laynard.I would recommend spending a few bucks more and get theWhiBal White Balance Reference Card - Pocket Kit (2"x3.5")instead.

Answer:
Negative
