Cordless

Can I get recommendations for a inexpensive but well made 3/4 inch or 1/2 inch CORDLESS curling iron? I have shoulder length straight thin/fine hair so I would
Like to get something durable that I can take with me that is not harsh on my hair so if I can touch up during work days I can OR one I can use if I’m running late and I have to finish my hair before I go in my office.
I have a Conair one that takes the ThermaCell butane refills but I don’t wanna keep spending more money buying refill containers since it adds up $$. With everything being so much more expensive nowadays I gotta cut cost where I can. Thank you in advance.
