I've had the same Sonic toothbrush for years and for a while, had difficulty finding replacement heads that fit. It says these replacement brushes fit all Sonic brands and they do for mine. Love my Sonic toothbrush!

[This review was collected as part of a promotion.] It was an easy fit to the toothbrush. The brush is a great size and works really well. My dentist loves this brand too. I have been a fan for 10+ years and will never go back to manual brushing.

[This review was collected as part of a promotion.] Excellent brush heads...does a great job cleaning without being to aggressive.I have had 5 gum surgeries and my dentist is thriolled with how clean my teeth are

[This review was collected as part of a promotion.] I have been using Sonicare toothbrush for over 25 yrs. My dental checkups have been A+ as per my dentist. The dental hygienist has told me that I have very little plaque and tartar thanks to my Sonicare! I would not use any other toothbrush.

[This review was collected as part of a promotion.] My teeth feel really much cleaner with this brush. Brush is also great for smaller mouth

Both products exactly what I ordered, delivered in timely fashion and in excellent condition. What mare can you ask - Sam's - bets shopping on line, bar none!!

[This review was collected as part of a promotion.] Appears to work better than my previous C1 heads and last longer. Will definitely will purchase again, just wish it came in a five (5) pack

[This review was collected as part of a promotion.] I've been ordering these for the past 2 years and haven't had any issues with the delivery and quality.

These Philips tooth brushes are a bit expensive. But well worth the price. I cut and damaged my gums on the cheap alternatives to this brand name. I recommend these.

Bought thinking it would last 3 months. My husband and I both needed to replace after about 1.5 months. Noticed a big difference in cleaning. Original head lasted easily 3 months. Dentist also noticed the difference. Will try a different replacement head.
