Quote from Timsixfour View quoted comment :
Listen I actually know a lot about this since my wife is in the dental field. 1 most important things always buy a brand name. You don't know how or what they are making the bristles with or if its harming your teeth. ADA accepted or nothing. Oral-B spin brush is the #1 toothbrush is the world for a reason, and it actually spins getting more plaque. 20-40$ for the oral B spin. This is a knockoff Phillips and Phillips isn't as good as Oral-B.
ADA means nothing. It's a paid certification that simply adds to the price difference. It's no different from JD Power, Kantar, Nielsen, etc.

Updated: I ordered one anyway. Good to have a backup electric toothbrush.

My cheap electric toothbrush from a few years ago is still awesome, otherwise I might get one.

Quote from Gngan View quoted comment :
Oral-B is number 1 in the world can be various of reasons. Marketing through commercial ads, dentists' push or they are a more well established brand. I've seen more Oral-B 'recommendation' from dentist than sonicare. It could be that they are really better or Oral-B pays dentists for advertisement. Not saying they are bad but who knows the real reason.
I have a bunch of oral b electric toothbrushes, but when I got my cheap no name electric a few years ago, I was blown away by the increased brushing power and many months of battery life (vs at most a few weeks of slowing down speed). I have no plans to go back to the very expensive oral B electric brushes: I'm sure some of the $100 plus ones are good, but I'd rather spend the price of 1 single oral b brush head for something I know is also good and has many brush heads.

So why didn't you edit out your original comment?....that's a total contradiction! It's also a good idea to read other posts, since I tested it and posted that it worked for non-prime members.
i don't understand your comment to me.

i read posts and the first response of "it works with or without prime" to taller238 was me at 02-02-2026, 08:50 AM

your first response to taller238 was 11 minutes later than mine. that's why my post is before yours.

i tested before posting. that's why I noted 12.99 before discount.

You need to consider that bait and switch is common with these no name brands and what they were once like in the past will surely not be how they are now. The whole idea is the first batches are good, and once the name/reviews look good enough, time to send out trash until the entire product and brand is burned to the ground and then rinse and repeat. It's why these are always wordsalad names because they dgaf.

Unfortunately I didn't get any email. Maybe I didn't fill out everything, but the warranty is in place now. Any idea what I need to do to get the email? I am on the regular email list from their web site.
