Take the guesswork out of watering

Blinking LED light lets you know when soil is dry. View larger.
Thirsty Light continuously monitors the condition of the soil in your potted plants, testing the moisture level once every second. The senor top features a small LED light that flashes once it's time to water your plant. While the sensor measures a total 6.5 inches, the green top is a mere 2-inches long, so you won't notice it until the soil becomes dry.
By letting you know when your potted plants need water, Thirsty Light eliminates the temptation to overwater plants. A comprehensive user and watering guide is included.
Light Blinks Faster as Soil Becomes Dryer
This sensor uses Drypoint technology, which can sense five different levels of dryness. As the soil gets dryer, the light blinks faster, letting you know how urgent the need for water is becoming. The included moisture signal chart explains each blinking pattern, as well as where to properly insert the sensor's probe.
The sensor also has a unique blinking pattern to indicate when the batteries are low.
Resilient and Long-Lasting Probe
Thirsty Light features an ABS plastic casing and a durable brass probe. With constant use, the probe will change color and develop a patina, which simply helps protect it from corrosion. If left in soil for long periods of time, simply wipe the probe with a damp cloth to remove mineral deposits.
Product and Warranty Information
The Thirsty Light is backed by a manufacturer's 30-day limited warranty against defects in materials and workmanship. It's powered by two included 1.5-volt lithium batteries that can be replaced when necessary.

On a side note, the water sensor is only two pieces of metal separated by plastic. I bet one could easily make one of these things with just an LED and a battery. Just a thought.
The concept, product appearance and packaging are all excellent. Unfortunately they don't work. As an initial test I thought it would be useful to compare the accuracy of the two sensors by placing them next to each other in the same pot. Hopefully, they would each begin to flash within 24 hours of each other when a dry soil condition was detected. I waited a few days, and then a few more. Finally I pulled them both out of the soil and found that the metal tips (anodes) on each one were corroded and the batteries in each was fully discharged (dead). A week earlier the metal tips had a brushed satin luster - similar to other moisture sensors I have used.
After jut six days in the soil they both became so pitted and corroded that neither steel wool nor sandpaper would restore them to their original appearance and functionality. Even with fresh batteries these pitted anodes prevented the sensors from functioning. Looking closely at my other moisture sensors they all seemed to have either stainless or nickel-plated anodes, and after years of use they still perform as new.
As I said, nice idea but ...an absolute waste of money.
Note: You can leave it in like I do, or save battery and just check the soil periodically.
