Review on LiyuanQ Upgraded Solar Powered String Lights: 2 Pack 8 Modes, 50 LED Waterproof Fairy Lights for Outdoor Garden Decoration - Warm White by Jeff Pettis

Never turns on the setting you want for more than 1 minute and starts looping through a few settings before dying. No amount of sunlight is enough. Poor quality and others also faced this problem. I tried moving them to other places in the house to get more sunlight but in the end they just stopped turning on because it was too late to return them. If you buy them there is a good chance you will get a broken one, I received two broken ones. Poor quality, just go to a real seller where you can return things that don't work.
