I purchased 300 lumify warm white bulbs after approx 10months the solar panel packed up. I e-mailed them and because of covid they couldn't at that time access the warehouse. I was told not to send repeat emails. So I waited it turned out some many months. in the end I e-mailed them again after maybe 10 months they sorted out the problem and sent me a new Solar panel with no charge. I just expected them not to do anything. I could always charge the the lights with usb. I think the company kept their word and the lights have always impressed me. I will use them again.
