Awesome Blossom! REVIEW UPDATED - Broke after 2 months.
This little gadget is awesome.  The only reason I am giving it 4 stars is because it took me some time to get acquainted with the settings and how they function.  I did read the manual which was helpful but in the end it was trial and error that got me through it.  Basically, if anything on screen is blinking that particular feature is in set up mode. You click the opposite button to then opt out and go on to the next feature.  The features are R, L, Temperature and Time.  Don't worry this review will clarify a few of your questions.  Once you get past how to operate the settings, it works great!  It is automatically is set to start on Celsius. The hottest temperature is 200 degrees Celsius which is the same as 390 degrees Fahrenheit.  Since I use it on the hottest temperature I leave it on 200 degrees Celsius so I don't have to change it to Fahrenheit all of the time.  If you want to change it to Fahrenheit you can do this by clicking both buttons together 4 times.  What I didn't know until after I used it is that you can change the direction in how the curling iron rolls, either clockwise or counter clockwise.  This is represented with an L for Left and a R for Right.  So next time I am going to reverse from L to R when I curl the other side of my hair.  Pretty neat.  Another thing to note is that you have to choose how many seconds you want to curl your hair.  I choose 8 seconds.  The roller will spin your hair for about 6 seconds and then stop. Do not pull your hair out yet.  It will begin to start beeping until the amount of time you selected is over.  The beeping will stop and this is when you can easily release the button and pull your hair out. If you abide by this feature you will ensure that you get even curls all around your head.  It works best when you use small bundles of hair at a time.  I tried to be lazy and my hair got caught up in it.  If this happens don't panic.  This device is actually really user friendly.  Just release the button and slowly push it and release, push and release until it unrolls your hair. Do not just yank your hair out.  I curled my hair at work during my break time.  I charged it at my desk with PC.  It was so simple that I did not require a mirror.  It was so convenient.  I loved not having cords to mess with.  It takes about 4hrs to fully charge.  Once fully charged it will last  about an hour.  It only took me 10-15 minutes to curl my hair but I noticed that I can only use twice without charging it or it will run out of power.  For this reason I make sure to charge it after each use so that it's ready for when I need it.  Make sure to unplugged it after it's fully charge so that you don't ruin the lithium battery.  If you do forget to charge it and run out of power it will operate if it's plugged in with a USB cord.  It is portable, lightweight and the outer casing does not get hot to the touch.  Not once did I fear I was going to burn my neck or hand. Love this!  Oh also, it will automatically shut off after 10 minutes if you forget to turn it off.  I highly recommend for adults, teenagers and even younger girls.  I just wish the settings will hold in place so that you don't have to go through this step each time before use.  Regardless, I am still on board! A+++  Enjoy!<br /><br />REVIEW UPDATE:  I am submitting an updated review because the curling iron stopped working after a couple of months.  I do not curl my hair every day and it still broke on me.  During mid-use the digital screen started going out on me and it began making one long continuous ringing noise.  I could not power it off no matter how hard I tried!  I had to put it in another room and let it ring for a couple of hours until the battery died.  I have not tried powering it on again in fear that the same thing will happen again.  It's as good as broken to me and I will not be using it anymore.  It was great while lasted.
