Curlformers question

in Hair Type 3
I have 3a/2c hair and I want to start using curlformers. They cost about 70 bucks Canadian so I want to get advice from people who have used them first! I want just open, "loose" curls. Can I achieve this with curlformers? Just generally looking advice and how versatile this produce can be. Thanks!
Edit: I am thinking of buying the barrel curl curlformers.
