What you get is basically one wand with 4 different size heads. You get one graduated/tapered head that goes from 1/2 to 1", a 3/4", 1 1/4" and 1 1/2". NuMe had a similar product on their page:
With the coupon codes I think you get these about half off. Maybe more. What I didn't like about the NuMe wands - the biggest thing is the lack of a heat setting. I have naturally curly/fuzzy hair and I like to have control of my temperature setting. I feel like I need more heat than the average person. The NuMe wand heats to 410 degrees. Period. No other options. The Cortex wands have an adjustable heat setting ranging from 360-430 degrees. Also, as it is heating up the digital temperature shows you the current temp as it's heating up. Pretty neat. Another thing I don't like about the NuMe wands is how they name their barrels in terms of millimeter size. The Cortex wands are named in inches. Maybe not a big deal, but easier. Simpler. I like it better.
From what I have read and researched on both of these wands, they seem to give very similar results. They both offer beautiful curls that really do last for days. I will insert a few photos of me using the different size barrels and the different looks they offer. I go on the average 3 days without washing my hair when I heat style it. The curls always hold up great and my hair stays looking pretty much the same the entire 3 day period.
1 1/2" barrel. I used bigger sections for a looser, more natural look. Gives more of a beach-wave look rather than a tight-curl look this way.
3/4" barrel. I used smaller sections for a tighter curl for this look. I totally love this barrel. One of my favorite looks the Cortex offers.
1/2-1" graduated barrel. Again I used smaller sections for tighter curls. These would've lasted all week if I didn't have to wash my hair!
Overall, I highly recommend the Cortex 4 in 1 curling wand. So much versatility with AMAZING results. It usually goes for somewhere around 200 bucks, found mine on Amazon for around $50. I think the NuMe wand would be very nice as well, I just chose the Cortex for myself. Let me know what you guys think if you have the Cortex or NuMe wands. Thanks and have a great day!
