Not Worth It!

I rarely file a negative review and these watering spikes unfortunately get mine. The theory is great. Put water in a bottle that attaches to a spike into your plants and it will deliver water at a chosen interval. It is all but impossible to regulate the water passing through the "spigot". It either all dumps out or not at all. I have tried over the course of several months to perfect this, because I really want it to work. So far no success!
