Overall low quality tester

1. Cons: Item does not illuminate as depicted in the photos. Results are difficult to see, and read, black digits on grey background. Results disappear unless pressing down on HOLD button while testing which can be difficult ergonomically. Instruction details are limited. Not enough data about deciphered results table. Lower quality than most other models reviewed. Inconsistent reading results. 2. Pros: Contains basic instructions which are helpful. Two testers in one pack.
