Yes I bought one a few months ago Squaredog.
My hair is short but not very short, IYKWIM.
I can manage the hairdryer, and it gives good results, (which I think is actually related more to the size of the brush than anything else), but it does take some getting used to.
I don't have any problems like arthritis with my hands but the difficulty is that the brush can rotate both ways.
You have to be sure that the brush is rotating the right way for that particular lock of hair, or your hair gets all tangled up 
I've got to the stage now where I don't really have to think about it but there was a definite learning curve and it isn't intuitive!
Next time I will get one that blows air but doesn't rotate.
However you can use the rotating one without rotating it.
Hope that helps.
