Work Great
I have been very pleased with these moisture sensors. I have a bad habit of forgetting to water my plants and having these have definitely solved my problem. I have been very pleased in how long they last and how accurate they seem to be. You can definitely see them turn blue when you add water and I haven't had a plant die since buying them.

Sustee Aqua Meter, Moisture Sensor Refill Insert,
These work well but not for large plants - they do work though for small to medium house plants

Cost effective?
So you save .89 when you buy the replacements vs the whole kit and caboodle again. Seems like a BIT of a fleece.

Highly Recommended
Thanks to this product, you no longer have to touch the soil to determine if your houseplant needs watering. Your plants will lose fewer leaves. I've purchased this product multiple times.

Works great!
These refills work as well as the original strip I purchased with the aqua meter. Great for plants that like to maintain moist soil or that prefer the soil to dry out between watering.

These refills are a waste of money. They've stayed blue from the day I replaced them. No indication at all if the soil is dry other than droopy plant leaves. Complete waste!!!! Do not purchase!!!!
