Seems ridiculous price to pay for a toothbrush but I got a similar version 5 years ago, battery still lasts 4 weeks. Teeth have never felt more clean.

I don't think it's the same model... Costco has its own model which doesn't have some of the smart feature.

"So I bought this two pack last year and it's okay. The toothbrushes have held up (as one should expect!). Pressure sensitivity telling you if you're applying too much pressure for effective cleaning is useful. I prefer the actual charging stand base to the inductive base cups (easier to keep clean for one, toothbrush is upright rather than semi-upright for another).
The biggest letdown is that Costco is selling the cheapest DiamondClean model. If you are buying it just as a Sonicare and don't care about the connected app at all - you're good to go. If you buy it caring about the connected app, this is the ONLY model of DiamondClean that's essentially useless for that purpose. All the connected app does is measure how many times a day you brush and how much time.
In contrast - more advanced DiamondClean models offer coaching to tell you if you're spending too much or too little time on different parts of your mouth. This is important if you're trying to train good brushing habits for your kids, another adult, or yourself.
Without true smart coaching, even at $90/handle this feels overpriced unless you really like the glass charger aesthetic. Otherwise you can get Sonicare models with similar cleaning performance and similar features (other than the pressure warning) for around $30 on sale."

It's not exactly the same but it has 95% of the features.

Bad quality, broken after 2 years. Based on the price, I'm not happy about it.

They work good. The marketing is so b/s. Just get a Philips soniccare around $40-60 range. The 5x , 10x 15x, 20x is a marketing scam

The heck you need a smart app and coaching for?
