Broke 10 months after I  bought it.
Although my first one broke in less than a year, the seller reached out to me and sent me a new one!  The wires inside of the old one had became disconnected.  I use this mostly as a curling brush though it works fine as a straightener too.  The barrel stays closed fine when you are using it as a curling brush. I have fine straight hair, but I don't like it too curly. The size of this barrel works well for that - not too small or too large.
