One out of the 4 didn't work and they have a mind of there own by changing modes on its own.Seem a little fragile but working great so far.Once you get the hang of the very thin cords and how to make everything, all will be well!!They look prettyhappy with the product. definitely would recommendVery bright light during night time. Love this little strip light, it is very easy to install, it comes with all kinds of models but this wave makes my front year looks very pretty. My neighbor stopped by and checking on my light. Great design. I am very happy for the priceI bought a two pack. I've had them outside for 4 days now to give them plenty of time to charge. One works, one doesn't.
