Query: Terrible quality

Ordered 2 of these, and the light did not work on either one. Additionally, one of them had a display that kept going off intermittently. Changing batteries did not help. One of them was obviously not finished: The light button was black, not painted, and the set buttons labels were not painted white but were still black on black so they could not be read. Obviously a real quality control issue. Sent them back and would avoid this brand/model.
