I have had this deck for a while now, and use it for myself and to help others. It's a great way to connect with the higher self and be aware of areas of improvement. The downside is that the cards are printed on silver-grey background - orange on silver, blue on silver, pink on silver - not much contrast, and those of us who are color-challenged have a hard time reading them without a very bright light. I have had to humble myself and ask other people to read the cards for me in situations where the lighting wasn't bright enough to distinguish the words from the background. Even a few non-color-challenged folks have had the same problem. In concept, I give it a score of 5. In usability, a 2-3. Maybe they should make a high visibility version for those of us with visual deficiencies. :(
