Loved the original so much, I had to hunt this down!
I know the 24k plating is gimmicky to those thinking it's just over-hyped "luxe" - but it is beneficial to those with extreme sensitivity to certain metals like nickel. I'm sensitive to nickel, but my original one doesn't make enough contact with my skin long enough to buy the 24k one for that reason. I just wanted something to match with my brush set. I love it, and although they urge you to toss your curler/pad [i've heard both] after 3 months of use, my own personal Shu has been with me for almost 6 years now, and I'm still on the original pad, not yet on the replacement pad. Just be gentle with these, and they'll last you a lifetime.
