These lights are very beautiful, bright, and sturdy. The ground stakes are plastic but the poles and housings are metal and the cover is a very thick glass. The housing of the lens throws a beautiful pattern on the landscape or sidewalk. Four-to-six hours direct sun contact is enough to charge them for the whole night. They have a light sensor and automatically turn on at dusk and turn off at dawn.  The rechargeable battery is housed in a water proof case. I would suggest to regularly clean the solar panel after 2-3 weeks and it would tremendously improve the battery life. I would recommend these lights both for personal use or as a holiday gift.
