Review: This thing is awesome!!!! 🔥🔥 - I honestly don’t understand the bad reviews I’ve seen — most of it seems like user error. They say they can’t connect it to the Edenic App, but they’re missing one key step: you have to put the Guardian into PROVISION mode first (Settings → Temp button) before pairing. Almost like it’s not written in the instructions! Once it’s set up, it works flawlessly. I get real-time updates on my phone if anything drifts out of range, so I can fix it before feeding and avoid pH lockout issues. Super reliable, super convenient, and gives real peace of mind. Definitely worth the money 👌 I really wanted to spend the extra to go with the PH dosing model but unfortunately it’s missing a sensor probe that I needed
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.
