Not great with normal unprocessed hair.
I I unfortunately have very difficult hair to curl.  So,  this just may be me.  I don’t have thick hair, I don’t have fine hair but it is very straight.  It hasn’t been dyed or processed in 20yrs.  So,  I know not the best hair for curls/waves... You have to use small pieces of hair in this waver.  It took me a lot longer than just curling or using my flat iron to do waves.  Once the long process was done.  My waves only lasted about an hour.  Was pretty disappointed.  It only has 2 temperatures might be why didn’t get hot enough?  Or maybe its my hair. I will probably give this away to someone with fine hair because of temp and amount of hair you can put in it.
