I have been using Andis flat irons for a couple of years now and I usually get the 1 1/2 inch size. I love that the flat iron gets pretty hot but I do have a problem with it starting to get cold before I can even finish flat ironing my whole head sometimes. My hair isn't that long, about shoulder length so it says alot that it gets cold about half way through my head since it's not like I have alot of hair to flat iron in the first place. Other than that I am pretty satisfied with the Andis flat iron, especially given that it was very cheap and affordable. I also love the size because it's not too bulky. I have owned several of these flat irons, and own two now and they have yet to give out on me. I have had to buy a new one before but that was only because the first one I bought broke due to my mom being careless with it. I'm no professional but I'd say this flat iron gets the job done like I want and it straightens my hair to my satisfaction without getting it too straight or damaging my hair.
