Query: very dissapointed with this horrible product

I bought this on a whim after my old curling iron finally bit the dust. I figured it was a good deal being a "2-in-1" straightening iron and curling iron. I tried it out the next morning and well...it was a mess. For one thing, when you plug it in and turn it on, there's a smell akin to burning plastic that quickly fills the room. I tried to "lock" the straightening iron in place so I could curl my hair, but the lock would never work. So I figured, well, at least I have a new straightening iron...so wrong. The plates have a large gap between them when you try to clamp them onto a strand of hair, which did me no good at all. I ended up wearing a ponytail, frustrated and a little nauseated from the overpowering stench. Do not buy this junk...period.
