I seldom give 5 stars. I gave 'accuracy' 4, b/c I have no way to verify the accuracy, but my plants are thriving like never before when I was trying to manage our hard water manually. Do follow the instructions for monthly probe maintenance (clean, rehydrate, calibrate), and you should get years of service from this simple well designed device. At worst, you may eventually need to replace the pH probe, at considerably less than the cost of a new pH pen device, which is essentially a disposable item (my Blue Lab pen was useless by my third season with it).
Best way to improve hydroponic garden results

Checking PH levels daily in a hydroponic garden can be a pain. Missing a day can mean a ruined crop or reduced quality.
I've hesitated buying this product because it is so expensive but I have to admit it is worth every penny. I regret not buying this sooner.
My plants are healthy, deep green and growing robustly. No more checking PH every day. This device gradually keeps my PH levels at 5.8 without worry or hassle.
Stop loosing quality and time with your growing...buy this now.

What did i do before this?

Hands down, the best 290 somod dollars i have ever spent. setup is super easy, calibration is super easy. I only had to open the manual to figure out which port was inlet and outlet (the left is inlet by the way). If you are dosing pH by hand, just stop.... stop now, and buy this. This product feels well built, no weird / sharp burs from cheap molding, the buttons have a good bit of resistance to them, the display is bright and crisp. My only minor complaint is it would be nice to have a longer wire on the probe and thermistor, but that is a trivial issue. 3 second dose every 2 minutes and my res was dialed in perfectly in just a few minutes. my only issue now is what to do with all the newly found free time i previously wasted meticulously measuring and adjusting pH....
Worth every penny

The media could not be loaded. Works exactly as described. Super easy to setup. No more checking ph multiple times a day. It's set it and forget it. Just calibrate when it says to. This item improved my quality of life. It just works. I dump in fresh RO water into the reservoir and the Bluelab ph controller fixes the ph within the hour. Growers, stop wondering if it works. It does. It's worth the price. Green light doesn't hurt plants in a dark cycle. I've got my system dialed in to 5.8 and that's where it stays. Love it.
Great tool to have.

Definitely makes things easier. Can leave my plants for a couple days and feel safe doing it. For the price I feel like having 2 pumps, 1 for up and 1 for down would be a thing.. but its good for what it is. Good buy.
