Review on 🌱 Bluelab METCOM Combo Meter: pH, Temperature, Conductivity (Nutrient) Monitoring for Hydroponics and Indoor Plant Grow - Easy Calibration and Digital TDS Tester. Pack of 1. by Kim Thompson

When I received the combometer I found that the pH sensor was not attached properly and the solution that kept the sensor active and 'alive' basically leaked and dried out in a salt coating around the cap. According to the Bluelab website, once the probe dries out, it can become permanently damaged, causing it to "die." After learning that an incorrectly processed pH probe had been sent to me, I started looking for a replacement and found many reviews going back a few years describing the same problem I was having. One reviewer stated that they have had 3 consecutive replacements/orders done in exactly the same way. Considering Bluelab's status as an industry leader, at least as far as I can tell, and also by far the most expensive piece of hardware, I consider it a failure to change their business/packaging practices and a lack of overall quality. Control is not allowed. Unfortunately I waited weeks from receiving the item to using it and the return window had expired. A warning to anyone who decides to shell out $300 for hardware, check it out now.
