I ordered the plant watering systems for when we go on our Alaska cruise and I didn't want to arrange for a plant sitter.
So far I have done a pre-trial run of a couple of weeks on assorted plants in different rooms and have encountered no problems. The plants look healthy and not over or under watered. So far only one of the systems when unwrapped was broken. All the rest were fine. I would order from this vendor again though. They arrived promptly and were perfect for what we needed.

We tried this on the Pothos hanging in our bathroom below a skylight, and the results are far better than we expected! No only isn't there a problem with the plant getting too little or too much water, but our Pothos is growing much, much better in continuously moist soil, rather that the traditional soak-and-allow-the-surface-to-dry-out watering method.
We've never had much success with indoor plants. Using the traditional watering methods -- allowing the soil surface to dry to 1" below surface, then watering until water drains from the bottom -- our plants usually suffered from older leaves yellowing and occasional brown tips.
The Plant Sitter was one of the more expensive automatic watering systems, but since it had the best reviews, we tried it. The results were surprised us.
With the reservoir sitting on the surface of the soil, in the center of the 10" pot (this is a hanging plant), the reservoir is almost invisible. And the soil in this 10" pot stays quite moist all the time. It feels like...how you might imagine the soil in a tropical rain forest soil to feel.
And the pothos just loves it! For 3 weeks now, it has been growing wildly, pushing out new leaves everywhere, branches reaching upwards and trailing down. Not one yellow or brown-tip sine we switched to the Plant Sitter.
With the house at 65 F, in March, and the plant hanging 7 feet below a north-facing skylight, about 1/2 liter of water is used up every week. I just returned from 1 week vacation and the pothos is thriving like never before.
I worried that the soil might be too moist, so I tried reducing the flow by covering the top half-of the cone with duct tape (to limit evaporation), then inserting the cone only 1/2 way into the soil. This produced no perceptible change in either water use or plant growth. I might try adding more tape, or figuring out how to lower the height of the reservoir. On the other hand, the plant is thriving so I may just leave it as it.
The key: Follow the directions meticulously, submerging the cone for a few minutes then putting on the cap while submerged, to ensure that the cone is soaked and full to the cap. You can't allow any air gap in the cone. To be sure, water the soil well before inserting.
Another key is that the amount of water transferred to the soil varie with the height of the reservoir. When we will be gone for 2 weeks, to be sure there's always enough water I plan to double the size of the reservoir, and place it slightly below the soil surface to slow the flow.
I can't predict how this product will work with other species or in other light. But for this hanging pothos, it's perfect.
