Sustee Aqua Meter, Moisture Sensor Refill Insert, Large Style, 4 Insert Replacement Sticks

seems like it works sort of... id still double check it with proper meter

I live in Phoenix, AZ and I use these moisture meters in potted succulents outdoors, specifically "Elephant's Food." Phoenix gets very hot in the summer, occasionally up to 120.˚ These plants require a very porous soil and should never be over or underwatered. The moisture meters make it easy. As soon as the meters turn white, I know it's time to give them a drenching. Using this method they grow wonderfully!

My fiscus was dropping leaves like crazy, either too much or too little water. Since using the Sustee sticks all my plants are doing much better. My monstera (swiss cheese) has now reached the ceiling and my fiscus coloration is much improved. I will continue to use them.

I like these when they work. There were two of the four that just turned green immediately and didn't work at all. That makes those that work very expensive!

I have been buying these semi-annually for some of my more important house plants. Great product to keep you reminded on watering.However, this time, one of them was slightly bent. There was no way to get it into the holder so I had to just throw it away. I was only given an option to return all 4 refills when I really just needed another 2 pack to be re-sent.

The refills turn blue after the first water and never go back to white. I took them out to let them dry completely and their still dark blue.

I have been using the Sustee Aqua Meters for quite awhile and have been very happy with them. Thinking it was best for the environment I ordered the refills. I ordered the small, medium and large refills. When I received them the blue water sensor paper was not securely attached to the sticks. They turned blue when I watered my plants but they never turned white to indicate my plants needed to be watered again. Even when I removed them from the soil and waited over a week, they never turned white. Past 30 days so I cannot return them.

watered the plants and waited then put in the pen and nothing. waited and still nothing. will not buy again
