This straightener heats up in such a short period of time, the beeping is helpful to know when it’s ready for use. It reaches an adequate temperature, no fuss or changing settings. It takes me approximately 20 minutes to straighten my hair completely, and I have naturally frizzy, curly hair. The health of my hair has not been affected by the straightener whatsoever. Highly recommended and wouldn’t use any other brand.
Contact GHD asap. That's how I knew something was off with my straightener. The first time it happened the same thing to me, I turned it off, removed from the plug and waited and tried to turn it on again but I still get the red light flashing on and off. I tried doing it for a few times but still had the same issue so I contacted GHD and they replaced my straightener but after a few months it happened again. It sucks because for the price we pay for these straighteners we expect quality but unfortunately it isn't the case with these products.
I own the GHD V Sapphire Styler and I am in love with it. It straightens through my medium to fine , puffy curly hair nicely reducing it to a sleek , straight and soft state. The box it comes in is really petty and you usually can purchase the iron as part of a set with another product such as a comb to styling spray, depending on where you get it from. It can be petty expensive but will last you the best part of a decade. The styler is create to curl, wave to straighten your hair and it heats up really fast and glides through your hair magically. However it makes it alittle bit trickier to curl/wave hair because it doesn't have much grip on your hair but usually the straighteners will gain alittle more grip the longer you use them (what I found with my iv styler).
This iron claims to heat up in 15 seconds; it also claims to use some bullshit technology that allows it to "self adjust" temperature according to hair type. Well it got warm but it sure as hell didn't heat up enough to seriously straighten or curl my hair in a mere 15 seconds--in fact, I found that it didn't ever straighten my hair enough to satisfy me.
For me, the first and still very best of all ceramic stylers [and my dad is a hairdresser too]. It heats up fast, cools down relatively fast, works wonderfully and lasts a long time. In 11 years, I've bought two such stylers. The first one eventually died after 6 years of daily use, rarely skipping a day, while my second one is still going strong. I have no reason to recommend any other styler but this one. My hair is long and very fine.
