These lights are nice but you have to make sure they are in an area where there is a lot of sun to see the full effect. They work best when you follow the directions and leave them in the sunlight for at least 8 hours or more by night fall you will see the full effect so far I havent had any issues with the batteries. I cant wait to see what they do in the summer . I can tell that in the Spring and summer these lights will be so amazing. Very easy to assemble it took me like 10 mins and thats for all of them not individual. You simply turn them on and attach the top to the stake and dont forget to pull the little plastic tabs that come on most solar lights to activate. Overall Id definitely buy more they are worth it.
