I've purchased a couple of these cordless curling irons over the years. Braun is a great product. The first one I had was black (which I preferred) & now they are sold in white with a matte silver-grey barrel. This iron is powered by replaceable butane energy cell cartridges which are easy to find in beauty supply stores & generally are sold 2-pak for $5-$7. The iron itself usually costs around $23-$25 and lasts for years. The iron comes with a removable hard plastic brush attachment. The clear plastic cover automatically turns the iron off if you pack it up while you accidentally left it on, and it makes carrying this iron around a joy as you don't feel any of the heat & therefore won't damage anything it touches right after you use it. I keep one at work & I always take this along when traveling. I don't use it often anymore but even when I did the butane cartridge would last far longer than I expected. I consider this product a very reasonable expense & definitely convenient. Full heat-up takes exactly 15 or 20 seconds, not even half a minute. Talk about speedy styling on the go! I can even move around as I'm styling since I'm not tied down by any electrical cords, and I don't need to worry about finding an electrical outlet to use it like I would with a traditional curling iron. It's size is compact enough that it's very portable even in a not-so-big purse. This iron is a lifesaver & a godsend, as I can either curl my hair with it or straighten & smooth it - very quickly, very easily, & very enjoyably. A must-have beauty tool. continued >>
