[This review was collected as part of a promotion.] i have used an electric toothbrush for as long as I can remember. For some reason, I had never tried a round replacement head before. I'm so glad I did. I felt like these did a better job of massaging my gum line, a well as getting small particles of debris out.m

[This review was collected as part of a promotion.] I love my Oral B toothbrush. It works well, and the replacement heads last a long time. With the cost of manual toothbrushes anymore, I'm glad I only have to purchase the heads. They clean my teeth well and they spin to get them extra clean. I'll buy these until my toothbrush doesn't work anymore.

[This review was collected as part of a promotion.] I’ve been using the Oral-B iO Intimate Clean refills for a few weeks now, and I’m honestly very happy with the results. 🔹 Comfort: These brush heads are incredibly gentle on my gums and teeth. The bristles feel soft and smooth, yet still manage to clean thoroughly without any irritation — perfect for my sensitive mouth. 🔹 Durability: One refill lasts surprisingly long without losing its shape or effectiveness. The quality of the bristles holds up well over time. 🔹 Effectiveness: Despite the softness, the cleaning power is impressive. My teeth feel polished and my gums feel healthier. It really reaches into those tricky spots! 🔹 Packaging: The packaging is sleek and hygienic — each head is individually wrapped, which is great for storage or travel. 🔹 Value: For the quality you get, I truly believe these are worth the price. A smart investment for a gentle yet deep clean every day. Definitely sticking with these for my iO brush! Highly recommended, especially for anyone with sensitive gums or who prefers a more luxurious brushing experience.

[This review was collected as part of a promotion.] My Oral B IO Replacement Brush Heads are great. Came in a two pack, which was great, one to share. The way they leave my teeth feeling so clean, is like no other brush head I have found or used. These hit areas that any other brush can't seem to find. It's like the Ultimate Clean of brushing. I want to recommend this style to all my friends and family.
