Review on Datacolor SCK100 SpyderCheckr by Nathan Jones

I had to shine a flashlight on the angel and study the spots on pink (A6) and black (B6) with my smartphone. card defective? Pros: 1. The case is not of poor quality. It is strong enough so you don't have to worry about it breaking.2. The cards themselves are thick.3. The retractable screw is metal, not plastic. Cons: 1. The retail box I received has a factory seal on the top box but not on the box where it can be easily opened. The size is a little big.
