I bought one curling wand at their North Star Mall kiosk in 2012. I honestly don't have any problems with it, but I don't use it anymore because I'd rather have my hair straight now.
I've recently gone back to the same kiosk because I was interested in buying a flat iron from them. A blonde girl from Israel told me to sit down so she can demonstrate how it works. She was incredibly rude and told me that my hair was damaged. She then asked me "So where did you buy your current hair straightener?" I told her that I bought it at Sally Beauty Supply. And she turned to her co-worker and said "Did you hear that? She bought her hair straightener at Sally's. Haha... No wonder..."
They try to sell you their products by insulting you so you can tell yourself "Oh maybe if I buy their product then I'll look beautiful"
I ended up not buying the straightener. I later found out they've been known to blow up. So glad I didn't buy it. I'll go ahead and buy a CHI instead.
