I had an old CHI dinosaur that worked perfectly for about 7 years. It finally started to kick the bucket a few months back. I have gone through 2 of the newer Chis in 3 months, they just stop getting hot.They feel lighter and clearly are nothing like the old ones. They do not do near as good of a job either. They are very different than the oldie but goodies. They definitely do not make them like they used to. I am not interested in a drug store flat iron I have very thick hair and need a pro. I tried the Babybliss and didn't care for it. The Sedu is ok, but not as good as the old CHI. Nothing works like my old CHI. But the new CHIS are not at all like the old one either.
