Plant Watering Devices Self Spike Planter Drip, Vacation Watering System for Indoor and Outdoor Pots, 10 PCS Set

It doesn’t work for me but it’s a great concept. You need to use a certain size of Coke or a Pepsi bottle and I don’t drink out of plastic pop bottles.

The stems don’t fit tight into the spike.You adjust them to work when your around and then you go away, to return to dried out plants and full bottles of water.Good concept, but components don’t give reliable water flow.

Great idea but no way to make it work with water bottles because of smaller twist off caps.

These didn't fit a standard water bottle, 16 9oz they may work with larger bottles.

It takes a bit to figure out the drip rate, but then it works fine.

I tried several different types of bottles and I couldn’t find one that doesn’t leak around the threads so it just kept dripping after shutting off the valve. The bottles were too heavy to kept causing my plants to tip over even after driving the spike deep into the soil. It doesn’t work for me at all!

This is a great idea however, the weight of the bottle made it tip over or just fall out of container unless one uses a very large planter. Depending on the size of the container it might be possible to prop it up.

I thought I was getting ones for water bottles but instead they fit pop bottles. I used 2 litter bottles and they last a lot longer.

Not fix properly
