I bought these to add on small bushes in the front yard, but a little disappointing because 1 of the 3 I bought would not work immediately even after putting directly in the sunlight for charging.  However, after about a week, for some reason it started working.  Thank goodness because I was just about to return for a replacement.  Although these are good for a small area to be lit up and the convenience of not having to run more plugs through the yard, the brightness of the lights are not that strong, but does provide a nice appearance.
