Easy install. Seem to be made well. They work well lighting our path. It's nice you can use your foot to push the stake in, but be careful, somehow a piece broke off of the end when we did. It's okay, we still were able to make it work, just something to be aware of. It'd be better if they made that part from metal. Otherwise they seem sturdy and were hoping they last well. Solar is a fabulous thing. Lights up our nights!!

Disappointing

Color: Bright White Accent Light

Terrible. I bought a lot of these, thinking they would be better quality, since they cost more than most of the other solar lights on Amazon. But they rarely all work -even in summer after some of the sunniest days. (Yes they are “on”). My husband bought some really cheap plastic ones, made by another brand, which average out about 2 dollars a piece and those actually work great.

Bought 4 - burned out in 6 wks

I paid full price and purchased four of these; within six weeks one was inoperable and won't turn on at all. Dead. One other is barely hanging on and two are still doing okay. Given the price, I'd expect far more.

Can’t recommend with 2/6 failing in 2

Purchased 6 lights, two failed within 8 weeks photo shows dead la get on left vs functional one on right. Sadly, I have received no response or support from the company. Who knows how long the other 4 lights will last.
