I looked at these loupes and light at a recent meeting to be used for a mission trip - they were average, but adequate for said purpose. I went forth with a contract for trial/purchase prior to upcoming mission trip. With the approaching mission trip, I said that I desired to go forth with the purchase. At which time, they gave me a price that was literally double the contract! We discussed and reviewed the contract and previous communications. I was told that management would not budge on the new year pricing. This was very disappointing to me and would question the integrity and trustworthiness of this company. My impression is that they are not professional and integrity is in question. I have discussed this with my colleagues and academic institutions & residency programs in their search for equipment.
