I love my ghd hair straightener and use it several times per week. It heats up quite quickly (in the region of 20-30 seconds) and heats to the perfect temperature for my hair. It's nice and light and feels comfortable to use. I find it less damaging to my hair than other cheaper straighteners, but find that it's definitely worth investing in some argan oil or other heat-protective product. Ghd straighteners are on the expensive end, but I think it's worth spending the extra money to buy a product that does a good job.
BEWARE of sellers with LOW FEEDBACK! Ask sellers questions about the 22 things I have pointed out above. If they do not answer, don't buy! If they make excuses, don't buy! Also, some buyers who have been ripped off are trying to resell their GHD's to cut their losses. Watch for things like "I got it as a gift" or "I recently cut my hair". One of the seller's I purchased from was supposed to be shipping out of Georgia but he really shipped from China. Don't believe everything you read about a seller's information. They can lie.
