The wireless timer functions. All functions can be operated intuitively. He sits comfortably in the hand. --- Vulnerabilities: The housing and the buttons on the transmitter feel as if they came as a gimmick of a gumball machine. The casing is very smooth and has no holding grooves. It misses a slightly out of hand. The font size and line width of the marks of status indicators (printed on the housing and displayed in the LCD) are extremely small. The letters have 0.96 mm height, the line width on the LDC is 0.15 mm. With the best will: A fast work or using at dawn are not possible. Schade is also the Li-battery of the receiver, which is unfortunately only available in specialist shops. Two AAA cells, as in the hand-held transmitter, would have done it safely. Conclusion: Good technical function, but the ergonomics was trampled.
