I bought a loupe light from this company during my D1 year. By early D4 year, the light already starting flickering and stopped changing intensities. The rep assured me that the repair would take a week, but they held onto my batteries for almost two weeks. On top of it all, they shipped it to the wrong address when trying to return the repaired batteries to me. I’m on week 3 of working on patients without a light and it will probably be longer now. Not only is their product poor in quality, the customer service is incompetent. If it weren’t for me still being in dental school, they wouldn’t have repaired the batteries. There are better products/ companies out there
