We bought 2 for $19 at Home depot and we like them. We got two boxes so we have a total of 4. You unscrew the solar tops and put the batteries in them and put them in the sun. We put them on the side of the pool during the day and toss them in at night. Makes it look cool at night. Lights up the bottom with different colors. When we get out of the pool we take them out and put them in our gazebo where we have two three persons swings. We sit in there till we dry off and some times have an adult beverage and the lights give off enough light to make it where you can see but not bright enough to be annoying. We like them.
