I was originally not pleased with the customer service regarding one of my products, but I think it's because my messages were getting mixed up between different individuals in the customer service side of the company. However, after escalating my complaints, someone named Josie ended up taking over and providing me with amazing customer service and ensuring personally that I was satisfied. She was on top of all of our emails, and did not rest until things were fixed. I have been using Lumadent since 2012 when I was a dental school student, and it's nice to know that the company is still reliable. I will never recommend or use any other company for my office headlight products.
