Whats the difference between the Olivia Garden Nano Thermic and the Olivia Garden Ceramic and Ion brush?

This is the commonality, they both have the ceramic and ion technology:Ceramic coated barrelHeats up faster& retains heat longerFaster & better stylingHydrates the cuticleAdds more shine to the hairEliminates frizz & flyawaysThis is the difference, the Nano Thermic has nano silver technology:Provides anti-bacterial protectionHair is healthier & easier to style

I have shoulder length hair. Can decide if the 2 1/8 or the 2 3/4 inch would be better.

My hair is very long but it depends on the size of the wave/curl you want. It really doesn't matter the size of the brush because you can change the width section of hair you use to wrap around the brush when you are blow drying it. You can opt for a one inch section of hair or more. The bigger the barrel of the brush, the more hair you can wrap around it. If it's a smaller barrel you can't wrap a big section of hair. For me personally if you are in doubt go smaller. I actually have multiple sizes of round barrel brushes if I want to make tight waves or not. If you are mainly just folding your hair under and then straightening with a flat iron, opt for a bigger barrel.
