These are super easy to put together.  Just attach the included stakes, turn on and put them in direct sunlight to charge.  After one full day of being in the sun, these worked as promised.  These are greant for accenting  plants or to add light to dimly lit areas at night. They are water resistant and won't rust.  Being in Florida we get our share of rain so that is a big plus for me.  I plan to buy more to enhance my yard at night time.
