Review on Boost Hydroponic Growth with PENCON Conductivity Temperature Nutrient System by Matt Welch
5 months/requires replacement
It was a surprisingly accurate pen but not fully waterproof, at least mine did. I couldn't photograph the small amount of water that entered through the battery cover seal because I dried it quickly without thinking, so I can't really prove water damage other than with words. It's been 5 months. This is my main pen and now it's broken. I'm not sure how or if I can get a replacement. Highly recommended.
- Cool product
