I agree with Peckish about the expensive irons.
A few years ago, I bought a Reliable brand iron that cost a pretty penny. Let’s just say it wasn’t so reliable, as soon after I got it, smoke started coming out of it. Not steam…..smoke. They offered to replace it, but I really didn’t want to risk using the same product.
Now I have a CHI iron from Costco. Not bargain basement, but not top of the food chain either. It handles everything I throw at it beautifully, and hasn’t started leaking or otherwise misbehaving after about a year and a half.
