I have been doing business with Harry at DHP for four decades. Great equipment at affordable prices and the longest warranty in dentistry. Compare the quality of Dansereau welds to any other dental manufacturer...you'll know what I know. They built equipment to last! Visit their factory and look at the stuff being made. I did. I see how they can offer a 10 yr warranty! You can pay more but you can't get more. There will always be a few sad sacks that are never happy and when you're a huge international manufacturer like DHP you're bound to run into a few people you cannot please but when you compare the Dansereau equipment line to others and then try to match their guarantee...it's easy to see NOBODY really competes with them. But you can spend more (a lot more) and get less. Just check the welds. LOL
