Product review (5 stars): Infiniti Pro quality to Art Naturals Spin Brush
I purchased the Infiniti Pro because the Art Naturals I owned and used for no more than a few weeks stopped blowing hot air and I didn't see the point of buying it twice.  My review is for the Infiniti Pro but also I put in some comparisons to the Art Naturals brush.  If you are looking at both this might be helpful.  My opinion is that you should not waste your money on the Art Naturals spin brush, buy the Infiniti Pro instead.  The quality is better in every way.  Infiniti Pro is performing really well and it's working reliably.  I really like the two wide brushes and find them to be gentler on my hair than the Art Naturals spin brush.  Both do a good job, the difference is in the quality.  We love our hair tools, there is nothing worse than liking a specific tool, getting used to it then having it die while your hair is still wet.  My hair is long, down to the middle of my back and both brushes were effective at drying my hair from the crown all the way to the ends.

Infiniti Pro - It is lighter weight than the Art Natural and the brushes are softer so they are easier on my hair.  Because it is a lighter weight I find it is much easier to use and maneuver.  I also notice that the softer spin brush isn't pulling out so much of my hair.  The heat settings are good, without getting too hot plus there is a cool setting if you prefer cooler air.  The only complaint I have about this one is the cord could be longer, another 12" would have made this perfect in every way.

Art Naturals - The heat settings are good, and they get nice and hot, plus there is a cool setting. The brushes are stiff, they do a good job they are just noticeably stiffer bristles. I can now say after using both that the Art Naturals was pulling out more of my hair (more left in the brush than the Infiniti).
