The product is very clever and I like the way it covers the teeth on three sides. I was using it for my son who has autism and he didn’t like it. It has very powerful vibrations which he couldn’t handle. Also the bristles were too soft for adult teeth. The vibration action may be too strong for younger children. I used the toothbrush myself and felt the vibrations were too strong for me. Otherwise it is a very good idea for brushing children’s teeth because it gets all three sides at the same time.My granddaughter loves itEven with brushing twice a day my kids were getting plague so their dentist recommended electric toothbrushed and I went the extra mile and got three sided brushes. It's been keep their teeth really clean! I don't enjoy how short the timer is but you can just keep brushing. I also don't like that toothpaste seems to get stuck inside all the bissles, I wish there was an easier way to clean it. I still haven't figured out how to get more replacement heads when neededThe toothbrush works well, and my special needs son can use it easier than a regular toothbrush. So far I am happy with the toothbrush and one of the heads that came with it. However, upon receipt of the package, I noticed that the extra brush head was....used. yes, used. (See picture) There are teeth marks on it and the plastic it was in was torn open already right out of the box....with all the people freaking the heck out about GERMS, you might think that this would not be sent to me used. My son was very excited to use the tooth brush, and so I will not be returning, as it's been used by him now, however I will be contacting the seller and requesting another head (unused, if at ALL possible).Like I said the brush works well so far, but really quite unacceptable that we received a used brush head. With food still stuck in it.This product is easy to use and I like that it can be charged instead of requiring frequent battery replacements. Unfortunately, when I tested it on my teeth (wanted to see what it would be like for my little girl), the vibration was so strong that it made me quickly put my hand over my teeth. It was very uncomfortable. I tossed it in the trash immediately.I read a bunch of reviews on electric toothbrushes and even bought another one before this. The one I bought works great too, but it doesn’t have the three sided benefit. My toddler hates getting her teeth brushed but she manages with this because it gets all sides of their teeth really well. It is cute, durable and the vibration has setting if they don’t like it too strong. I would definitely recommend and I will keep using for my daughter!!My son hated brushing his teeth. It was a total nightmare. I got him this toothbrush and he loves it. Not only is it easy for him to use himself it cleans his teeth really well. He turns it on and it turns off when the time is up. So he knows when its time to stop. I love it and its a game changer. I highly recommend it.My children's dentist suggested that I purchase a toothbrush like this one for them (they are both autistic) since brushing can be difficult for them and their sensitivity issues. The bristles do brush 3 sides of their teeth and has an automatic timer. The first time using it might feel weird to them but they got used to it right away. My son said his teeth feel "really smooth" after every brush. I have noticed their teeth look very clean since they started using it. My 8 year old still has most of his baby teeth and my 10 year old has all his adult teeth and the brush works fine for both of them.My kid loves itMuy prácticas las botellitas
