barely made a wave [SEP] i have been trying for well over years to get a curling iron that actually did what it was supposed to curl my hairhot curlers no good resultscurling irons no good results wrap around fabric curlers nothing therei saw this and thought it couldn t fail simple to use plug in turn on heat up section hair and use put hair in count downworks in theory fails in execution first up there is no heat seating guide for safe curling this device is celsius c only no farenheit f option google is strongly needed hereaccording to redken mistakes to avoid glamour drill it into your brain you should hold an iron on your hair for eight to seconds max along with using thinner groups of hair i should have some wave nope i even went seconds nothingas my hair has become a bit thinner has been color treated and exposed to so much i wasn t about to turn this up hotterthe curler is designed much like a crimper but the width can make it difficult to handle especially by yourself there is a guard which heats up as well and it is easy to burn yourselfit wins with innovative idea as well as the digital temp gauge also it does heat up super fast as well as cool down just as fast when lowering the tempfor use by myself this is a two star deal perhaps if someone else were around it might be easier but this definitely did not work well
