Review (4/5): Works great with duct tape
This is my second purchase of this attachment. I really like the result I get using it and it cuts down the time and heat required for the flat ironing step. Although multiple rings are included to ensure a good fit, this never really fit my dryer well. I considered buying a new dryer, but my little dryer still works great. During most uses, I had issues with the attachment popping off until the dryer heated up. Although, even then, I still had to use both hands to keep it secure, work slowly, and make sure my hair was detangled well. Over a couple of years of use, the attachment started popping off constantly, so I took it apart and noticed the rings had started melting and losing their shape (still without damage to my dryer). With this 2nd purchase, I just opted for the duct tape. It's not the most elegant solution, and I will check it frequently to make sure that nothing gets damaged, but it works.
