It was a breeze to set up - just peel off the plastic tab off the top of the solar light, open the battery compartment (it comes with an AA battery), and screw the lid to the solar light. Add potting soil to the container and plant. Connect the trellis piece to the container and it is ready.
Place the planter in a sunny area. I have it outside our kitchen nook window, not the sunniest of spots but enough for it to work for a few hours at night. Mainly, I wanted to put it in a spot where I could easily observe it from inside the house. It would be perfect for a patio which is where I intend to move it next spring.
The light casts a soft, opaque glow that illuminates the plants in the pot as well as lights up the surrounding area. The light stays on for about 4-5 hours for me and again, that is with limited sunlight. I look forward to trying it with different plants and locations in the spring. After almost two months, the battery is still going strong.
