Отзыв о Вращающийся фотосинтетически водонепроницаемый телескопический прибор от Dave Stewart

This industrial and scientific product promised to accurately measure light but through trial and error, I found that it fell short. The waterproof feature was a plus, but the rotatable design made it difficult to get precise readings. It also lacked clear instructions, leading to confusion during use... Overall, not worth the investment in my opinion..
