The size of the lights are nice, not too big or small. The ground anchor is easy to twist on and off and is durable when placing into the ground. Make sure the dirt is dug up a little to provide less resistance. They function very well. The lights are bright, maybe too bright if you look directly at them. Otherwise, they work as intended for lighting a path or garden accents. Ten dollars for a two pack is a little steep but you'll save money if you buy the multipacks.
