Terrible. If you follow the instructions, the results will be the same for all modules. I can't trust that. It is nearly impossible to get accurate measurements on a sample as the numbers jump up and down when just sampling pure water. The ORP reader is very slow to display results. The temperature is the only thing I can trust. I do NOT recommend this product.
