Query: Don't Waste Your Money

This iron is NO GOOD. I should've known not to get a REVLON curling iron. Revlon are known for make up & nothing else! My on/off buttons didn't "sink" in until about a year after I had it. The curls didn't hold very well 'cause it didn't heat up that well. Maybe this is good for people with very fine/thin hair though. I wouldn't recommend it. Spend an extra $20 or so and go for a reputable curling iron brand.
