I received this product for free in exchange for writing this honest review. The curlers come in a compact container that you simply just plug in. I have found that if you leave it to warm a little longer, the curls tend to be a bit tighter. I just simply parted my hair in different sections and picked the size that I wanted to use. The smaller the curler, the tighter the curl. The bottom of the curlers tend to get extremely hot and you have to be careful to not touch that part when rolling the curler into the hair. I also found that sometimes the pin doesn't go on easy or hold it tight but I simply just try and move it a little and it usually works great. Personally I would prefer more of the middle or large size curlers and not use the small curlers as they do make very tight curls. Next time I may just not leave the smaller curlers on as long to see if it makes them more loose.
