The product itself looks like it was made in foreign lands for 25 cents, if u pinch hard you could break it-straight overpriced plastic. The touchscreen takes 5-50 clicks to register anything. Very disappointed .Will be returning . ### 3/5 — Absent radiation in the menu *2025-10-25, version 1.8.7* Where is radiation in the menu ? ### 1/5 — Не советую покупать *2024-11-21, version 1.8.6* Производителю следует задуматься о доработке этого устройства. Идея хорошая, но свою функцию не выполняет. У меня есть прибор для измерения PPM, но это устройство с каждым измерением показывает разные показатели. Игрушка, не более. ### 1/5 — Nie da się zalogować a urządzenie się odłącza *2024-02-26, version 1.8.6* Sałbe ### 1/5 — Не подключает тестер *2023-07-28, version 1.8.6* Не подключает тестер, не проходит регистрацию через email ### 2/5 — Перестала работать *2022-11-02, version 1.8.6* Пожалуйста сделайте иконки больше, или дайте возможность менять интерфейс самостоятельно. ### 3/5 — Fruits et légumes manquants. *2022-09-15, version 1.8.5* Il serait temps de penser à ajouter les fruits et légumes manquants depuis des mois et de nommer certains d’entre eux en bon français et non en traduction aléatoire. ### 1/5 — Не работает! *2021-07-04, version 1.8.0* Почините в приложении функцию радиации и измерения жесткости воды! ### 2/5 — Странный девайс *2021-05-23, version 1.8.0* Нитраты промеряли, за точность измерений не ручаюсь, сравнивать не с чем пока. В приложении отсутствует возможность измерить радиационный фон, батарея заряжается на 50% и дальше не заряжает, либо индикатор не показывает. Посмотрим, как дальше себя проявит. ### 1/5 — Не работает измерение радиации *2020-08-06, version 1.3.6* Я всего 1 из 10 раз могу измерить радиацию. И то криво, почему не работает этот функционал? У меня на приборе эта функция есть, а в приложении не даёт нажать кнопку «измерить» ## Frequently asked questions about Greentest ### What can Greentest analyze?
