Sharing my results using the Spornette Square Heat Stylers Brush.
This brush has a square aerated barrel. I found that my drying time was much faster. 
Using the flat side, I could blow dry the hair straight including the ends. Using the corner of the square I could get a flip or curl on the ends. By doing a twisting motion while drying and using the corner of the square, I could get waves.
The Spornette Square Heat Stylers Brush is a versatile brush that allows you to get different results.
The Spornette Long Smooth Operator Brush is described as a “one piece ouch-less handle reduces tangles and snarls. Each brush feature Ions or Tourmaline powders which emit ions when used with styling tools. These ions breakup water molecules, reducing brittleness and permitting the hair to be more soft and stretchable”. 
The longer barrel did reduce my blow dry time; plus the combination of the ceramic thermal barrel and tourmaline ionic nylon bristles resulted in a smooth finish. 
I got great results using this brush.
The Spornette What A Gem brush came in this lovely packaging and included a free Gem clip. The description on the back tells you all the details and use of the brush. 
I love the look of this brush and it is lightweight. I like that that the head of the brush is all one piece and not vented; that way you don’t get product buildup inside the brush and since the backing of the brush and bristle area is one piece it will not come loose while brushing.
Here is a video of the Spornette What A Gem Detangling Brush in action. I used it on myself and my girls. We all have different hair types. I have thin curly hair. One of my daughters has thick wavy/curly hair and my other has thick straight hair.
Like I said in the video I use a wide tooth comb to detangle my hair. Sometimes I use a brush to distribute product in my hair but only after it has been detangled. The brush worked great on my hair. But the biggest test were the girls. My youngest gets a lot of tangles and knots. So, I own quite a few different name brand detangling brushes, all of which she has complained about. This was the first time I could detangle her hair without a complaint.
I am very impressed with how well What A Gem detangling brush worked. What A Gem will be my go to detangling brush, especially for my girls.
