It's a bit heavy [SEP] This diffuser does the job.  I have medium length, thick hair and because of the large size of the diffusing area, the amount of hot air it produces is just fine.  It does not over dry.  It is heavy and large.  It is not good for traveling but I kept it because it does stay on my blow dryer....unlike some diffusers that pop off.  If you have good arm strength, its a no brainer.
