The dental loupes are very nice. I haven't used them long so will update on that after I've been using them for a while. Just wanted to comment on the experience of purchasing the loupes and contacting and meeting the sales rep. (Location: MN). 1. The sales rep did not seem professional upon our meeting. She would be on her phone sometimes during the meeting. The meeting with her was to measure my working distance as well as just informing me about the loupes I was interested in. 2. She said I would receive a second pair of safety glasses where I can mount my light free of charge with my order but they never came with it when I received my loupes. 3. After I ordered my loupes, I did not get any emails about the order details or a receipt. Thus, I had to contact her again to get a receipt for my records. She kept saying that Lumadent will automatically send me updates on shipping and the receipt but while waiting for the loupes for 4-6 weeks, I never got any order or shipping details. This would have been nice to have for my records and inform me on updates of the package. Overall, didn't really enjoy the experience with ordering the loupes. I wish the experience with the sales rep was better.
