I love my curl secret, its the easiest gadget I have ever used but its costly. maybe those bendy rollers or twisting hair into small buns with soft scrunchies would give the individual curl look. I don't like using heat appliances too much as they dry my hair so when its almost dry I twist into a high bun and leave overnight, when it comes out in the morning I have lovely waves, smaller versions of this give tighter curls. like the old rag curlers used by my grandma.
DD2 has this one Baby curls it's great for a ringlet type look, they also have bigger barrels (which DD1 has0 which give a bigger/wavier look and I think one in between! They do get hot and there is potential for burning but they supply a heat proof glove. Having said that DD has used hers since 13 and never burnt herself unlike her cack-handed mother
