Overall, it's an excellent tool for optimizing plant care and improving nutrient management, offering great value for the price.

### ⭐⭐⭐ Temperature output and disc drive
*by G***V on July 29, 2025*

Generally good, but the temperature output is more closely related to the air temperature. It could be my mistake in assuming it would measure leaf temperature. It would also be good if the software could be accessed another way, as most computers these days no longer have disc drives.

### ⭐⭐⭐⭐⭐ It works!!!
*by F***G on September 25, 2025*

Works amazingly, as described. Pretty accurate to my other more expensive meter, also relatively sturdy. Fair price to save your plants a lot of stress !!!
