I have spent years looking for an LED substitute for the vintage C9 incandescent bulbs. I found these online and thought it was too good to be true. I placed an order for both twinkle and regular bulbs. The next morning I realized I didn't order the right ratio of twinkle/non-twinkle that I wanted. I live chatted the company hoping someone would get back to me eventually. Brian answered right away! My package had already been prepped to ship, but he tracked it down and got the bulbs switched out. He was knowledgeable and had great advice on what quantities I should go with. The package shipped less than 24 hours after I ordered it. The product was just as pictured - I couldn't be happier. I have a few strands decorating my home and I will be ordering all my christmas lights here in the future.
