Review: High value for price for the "prosumer" market - I only read negative reviews to gather my opinions on a product. If you're serious about buying a product like this, consider that pH probes are not a lifetime investment due to their nature, and move on with life. This unit has a permanently fixed EC sensor, and a replaceable pH sensor. I've purchased two of these units. The first came out of the box and required no calibration as far as I could tell. The second unit came with a defective pH probe (again reference why these probes are problematic in general regardless of manufacturer)... Immediate and awesome response from Bluelab support and they are sending me a replacement probe with no issues. The reviews I've read about this company are consistent with my experience, and I cannot recommend them more. If you want to integrate your own app with their API, it's braindead simple. I cannot recommend this product more.
Review: Fantastic service, great product, can’t compare to anyone else - Fantastic customer service! Comes with warranty and they are super quick to replace broken parts will definitely buy agin.

### ⭐⭐⭐⭐⭐ Perfect accessory for my Tower Garden
*by D***T on October 24, 2013*

This makes monitoring my PH , temp, and TDS levels easy. No more having to take samples of the water to check my PH levels, or wondering about the temperature of the water feeding my plants. I'm currently using the TDS meter as an indicator of my water level. As the water level goes down, the concentration of nutrients in the water goes up... I think. So as the TDS level goes up, I know that the ratio of water to nutrients is going down (since I know I did not add any nutrients during that time). Don't quote me on this. I was never any good at science or math. Anyway, I don't think I'm using the TDS meter properly, but what the heck. It works for me. I love the product. I just wish the cord for the PH measuring thingy and the temperature measuring thingy were longer, but now I'm just nitpicking.
