I used the older version of this product (GHD Salon Styler) for 15 years until it died a year ago. I received the GHD Gold 2 months ago and I'm disappointed.
I have thick wavy hair and with the old GHD I would only need to run it through a section of hair 2-3 times for the pin straight look. However with my new one I'm running it through as many times as 5 which I don't think is good for my hair.
It takes a lot more effort than it used to and even though my hair appears straight it does tend to look 'fluffy' which is frustrating after putting in all that effort. The protective guard is not designed for travel - it will come off in your bag as I found out.
On the plus side the GHD curls wonderfully (just like the old one) and I really like that it beeps when it's ready for use. With the old version you had to watch the light until it remained solid to indicate it was ready.
Out of all the straighteners I've used, GHD still comes out on top it's just a shame this new version doesn't give me the same results. My friend still has the old version and it doesn't disappoint.
I cannot rate these highly enough. Born with extremely curly hair I believe I have tried almost every hair product or treatment available. They are easy to use, quick and effective and the results last for days. Definitely a girl's best friend. Price may be higher than other options but in this case you definitely get you money's worth. Worth every penny!
