I could test the So Curls Calor through the site Sampleo and I just give you my opinion. Here is finally a device that makes all alone, that wrap the strands and creates different loops. The Iron grip curling CALOR SO CURLS is very simple, which I'm not very good I found it easy (instructions with explanation if needed), but once understood it going alone. In addition the So Curls is adjustable to the temperature level, and three different settings can also be created out of different loops (tight, flexible, corrugated ..) and choose the rotation of the loop. Take the helping hand and here we are with a beautiful curly hair .. But attention once the device is locked if it is hard put his lock of hair but nothing too bad that it does not remain stuck in the machine: p . I recommend this product.
