Andrew, the DELight appears to be a well designed Erbium. I particulary like the small profile handpiece with the curved tips which allow excellent visualization of the preparation.
I use DELight since more than a year an a half and I can say that it’s a pleasure to work with.I do more than 50 % of my day with that laser without anesthesia and it’s a relaxing to see so much people walking out of the office and smile. The new 90 degrees tip is a must for all the teeth including the molars
