"I've had Nexplanon for 18 months and for me it's working well.  Had one period right after insertion and spotted only once in 18 months since.  No acne.  And my migraines have been much less frequent and less intense since getting Nexplanon.   However I have gained 18 lbs. despite significant reduction in calories and increase in exercise.   For that reason I'm having the Nexplanon removed soon and will try Skyla instead.   If it weren't for the weight gain, I'd give it a 10."
