Dr. Hauss is a quack. After paying over $10 000 over a period of 4 years, Dr. Hauss has left the job of straightening my teeth unfinished. Dr. Hauss has the digits of a primative aveman and I wouldn't let him work on my bicycle. He had no business in attempting anything other than Invisiline, there the calculations are made in a lab via computer and he is somewhat uninvolved. Do not go to this guy, for anything, you'll end up overpaying for crappy service and he'll probably mess up the job or break something else in the process..
Cons: Is there more space?
