Title: This model not recommended
Review: Great idea but more tech development is needed for this version. Screen reflects too much outside light obfuscating the LED numbers. The numbers have low contrast and their improvement is not achieved by the technique suggested to where they can be easily seen. The lines between the groups of 9 square blocks are not prominent enough making block determination difficult. The unit is actually hard to see clearly to be enjoyable to use. I would skip this model and investigate other manufacturers editions.
