Well worth every cent.
The solar battery on this is amazing! It runs from dark to light. It has 2 modes. To you can have it really bright or just light. Easy to install! The quality and functionality is well worth the low cost!

Not very bright and replacement bulbs expensive
Size: With 91.88" Tall Post
With only 260 lumens it's not very bright. Replacement light bulbs have to be purchased through the company and are very expensive. Cannot find bulbs outside the company that fit and they do not offer brighter bulbs.

I think they look smashing ...as my British friend would say!
My goodness I absolutely love them. Yeah they're plastic but they really are lovely. Easy to put together and by the way, I'm 85 year-old young lady, and I did it all myself big deal… I hope they last a long long time because they look really spectacular on our driveway posts! Oh, and they give the needed lights that I was hoping for I really like them as you can tell. I'm heading off for a bridge game right now but tonight when the lights are on, I'll take a picture and try to add them here. I really really think they're lovely.

Bright idea
Burns bright. Lasts all night. Took more time to unwrap than it did to install

Looks good but but takes work to put it together.
Parts do not fit together well. Had to take a knife to trim top to make it fit. Plastic nuts and bolts. Light works well and stays lit for hours.
