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.
Sharing my results using the Spornette Ventura Blow-Out Brush.
The Spornette website description: “Ventura Brush is a hybrid brush combining the best of a round brush and a paddle brush. Curl, flip or straighten all with one comfortable and convenient tool. The Ventura’s flat side is great for straightening and the round side is great for curls and flips. The width of the brush can work on larger sections of hair. The elliptical design helps pull roots straight and smooth out ends with a simple twist of the wrist. The twist will help lock the brush for a smoother Blow-out. The metal barrel on the paddle side of the brush is great for smoothing & straightening.
The rounded sides of the brush are great to curl or flip ends.” 
The brush is light. The handle has a perfect grip and design to facilitate the movement of your thumb and hand during the drying processes. I could get great tension on the hair, which is something I only got using a round brush and never with a paddle brush. Once I found my rhythm using the brush it was easy sailing for this blow-out. I was able to use larger sections of hair as I moved up. Got a great blowout in half the time, which made my kid happy
It really was a joy to use this brush, love it.
