Works great!

I'll start by saying I ordered my Sam-1 from the Sensorex website and received a defective meter. However, I am VERY satisfied with the customer service AND the performance of my replacement product. Paired with the Sam-1 meter, the app works flawlessly on my iPhone 5s. When compared with a stationary Oakton pH meter (+$900 retail) the Sam-1's pH readings take noticeably longer to stabilize but the accuracy is much better than expected for the price of the meter, plus it has the convenience of portability. Very happy with the product, and the performance of the app.
