Babyliss sublim touch

Been looking for a flat iron for the longest time and wanted to ask for opinions on the babyliss sublim touch. For context, i have frizzy curly hair and my main problem with using blowout brushes is that they nvr are able to tame my curly roots and when i wake up my hair basically just goes back to curly 😭😭😭 so yup im looking for a hair straightener that can straighten my roots and make it sleek as well as lasting results at least for up to a few days?
