I do think that the clampless curling iron is worth it - whether that means removing the clamp on a traditional curling iron or if that means purchasing a clampless. My hair is notoriously difficult to curl. I've tried hot rollers and various traditional curling irons. I purchased a ceramic clampless on Gilt one day and the results were simply amazing. My hair was actually too curly and the curl lasted literally all day long. I was told that if I want the curls to be looser, I would need to wrap larger chunks of hair around the barrel. I'm still practicing, but I am thoroughly impressed. Another trick with the clampless, is that you hold it upside down (with the handle in the air and the barrel pointing straight down to the floor) and then wrap the hair around it. You just grab sections of hair, wrap it around the upside down barrel, and then slide the curling iron out from the top. At that point, you just let the curl sit and cool (it hangs as a perfect ringlet). The whole process goes pretty quick and I have long hair (it is at least half way down my back). I think that if you have a good CERAMIC traditional curling iron, go ahead and try to remove the barrel. If you don't have a ceramic, then I would suggest investing in one and you may want to consider the clampless version.
