[This review was collected as part of a promotion.] Got these and they work wonders. Packaging was great. Easy to open and easy to install on the toothbrush. The Brussels were just right when using, they were not to soft and not to hard. Just right. Definitely worth buying more.

[This review was collected as part of a promotion.] I got this item as I was expecting to use these on my existing O-ral B power head. They are not compatible with my existing power head. In order to use these you will need to upgrade to the iO O-ral B power head. The packaging was sufficient and they arrived undamaged through the mail.

[This review was collected as part of a promotion.] I could not find any difference between my original brush heads and these other than the vibration, which really did not add extra benefit. Both are top quality. The only difference I saw was the color; the new ones are black. I've had these for two weeks. switching back and forth between them. There is literally no cleaning difference between them.

[This review was collected as part of a promotion.] I've been using these brush heads for a while and they never disappoint. They fit perfectly with my Oral-B iO toothbrush and leave my teeth feeling incredibly clean. The bristles are gentle on the gums but still very effective at removing plaque, especially near the gum line.

[This review was collected as part of a promotion.] I love a restock on these oral clean refills such a durable refill. I love a great product for a great price. Scentless and great comfort for the teeth . Leaves a great odorless mouth effective for a clean oral hygiene.

[This review was collected as part of a promotion.] Well, I want to tell you my opinion about this product. Let's start with the packaging, it is very original and beautiful. The design of the brush is great. It is easy to use, cleans your teeth well. The price corresponds to the quality. It will serve you well. It is very comfortable. I have been using it for a long time))))

[This review was collected as part of a promotion.] I am very picky about my toothbrush due to tooth sensitivity. These toothbrush heads are not too rough on my teeth and gums. Over the course of two weeks, using Crest whitening toothpaste, I have seen my teeth become whiter with twice a day use of these heads. I am switching my entire family to using them.

[This review was collected as part of a promotion.] I haven't noticed any whitening but I do like the feel of it. My dentist will be the final judge. The feeling of clean teeth and healthy gums should be the goal of your toothbrush. Buying this is a great start towards that goal, toothpaste and floss are the rest. Assuming you have a toothbrush to attach this to!

[This review was collected as part of a promotion.] Have been very happy with this product so far.with so many to choose from,I wasn't so sure about them at first,but very glad I decided to try them.The bristles are soft enough for my gums,and also firm enough for my teeth.

[This review was collected as part of a promotion.] I received this product a week ago. It work really well with my original battery operated toothbrush. It was easily to install and attached to my toothbrush I already own. The brush are nice and firm and fell great on my teeth. I will be using the product from now on. I recommend this product to anyone who interested.
