I just saw the infomercial the other day and it looks good. I called to find out what the cylinder is made of and they said it's a brushed aluminum and it has a little roughness (but not a lot), which is what causes the hair to shine.
I'm curious too about it but I am waiting for my shipment for the KStyler which looked really good with the floating plates for flexibility and even heating.
I'm going to try the KStyler for the trial basis and then order the InStyler for a trial and see which one is better. At least with the Instyler you get two.
I tried looking for reviews and can't seem to find any. It's pretty brand new.
