BaBylissPRO Nano Titanium Ultra Thin Flat Iron 2" vs BaBylissPRO Nano Titanium 1½" Flat Iron

Both are BaBylissPRO Nano Titanium ultra-thin irons with the same 450°F ceiling and titanium plates, so straightening results are close. The 2" model gives you a wider plate for thick or long hair and 50 heat settings for fine control, but it is bulkier in the hand. The 1½" model adds digital temperature presets, dual voltage, a 60-minute auto shutoff and a 4-year limited warranty, which makes it the better travel and safety pick. Buyers rate the line highly for fast, glossy straightening; the main complaints are the fixed high heat on lower settings and the plain plastic body.

• Choose the 2" Nano Titanium if you have thick, long or coarse hair and want a wide plate plus fine-grained heat control at home.
• Choose the 1½" Digital Nano Titanium if you want digital presets, dual voltage for travel, auto shutoff and a longer warranty in a lighter plate.
