Sönik: 2 Replacement Brush Heads

My toddler actually lets me brush now since these heads are so much gentler on his gums. The two-pack means I've got a spare ready when the bristles start to wear out.

Fits the 3-stage ultrasonic toothbrush perfectly, and the bristles feel firm enough to actually clean but gentle on gums. Only gripe is they seem to wear a bit faster than the original ones, but for two heads at this price it's a solid deal.
