I love the machine. Just like everyone else, we need a smaller tip only for use in those areas where you can't use the regular tip: Nose, knuckles, and some really bony areas of the forehead that are curved. that would pretty much make it perfect. I saw some complaints about cost, and I'm assuming that none of these people have had one of these treatments in a medical office. I have at $250 a pop, probably more in metro areas. So I am just tickled pink with the costs of the machine and the refills! Thank you, Dr. Denese. I just love you to pieces!
