Can we stop pretending that phone numbers are required for online transactions? I've never once received a follow-up phone call with questions about my order.

Payment confirmation is usually instantaneous, and my address is typically required for the payment information and/or shipping if there are questions.

Hard not to believe that my phone number isn't being used as a unique customer identifier and thus collected entirely for the sake of collecting data.

In response to this post

Obviously the former, having the battery completely fail to hold a charge after 9 months is unacceptable and I'm not sure that's a fluke or a misinformed review. It seems almost too awful to believe that a top-line brand like Sonicare would make something like that. 2-3 years for battery life is a bit more palatable, but it seems like the corded varieties of toothbrush handles are all but nonexistent. Indefinite support for brush head replacements is obviously the main driver and a must-have.


@paulknightly I have a sonicare. A) didnā€™t think it would be much different than a manual brush, but I definitely feel cleaner. B) Iā€™ve had it for over a year and thereā€™s no noticeable battery degradation. It holds a charge for >2 weeks of once-a-day brushing.

I'm finally following through on the advice of my dentist to get an electric toothbrush. I haven't owned one in probably 15+ years, in part because models at the time weren't particularly sustainable and I found myself replacing the entire toothbrush every year or two.

Digging around now I'm finding conflicting reviews and testimonials of rechargeable toothbrushes needing to be entirely replaced either at 9 months or 3 years for the same model. Any recommendations from my feed?


@paulknightly Tha always has annoyed me, they tend to be on the consumerism/infinite refill train. There are some brands with readily available head replacements, though.

I can confirm that I started seeing these posts cropping up in my Instagram feed around the September time frame that Meta reports as rolling out the feature. I tried to "show less" of the posts, but that only increased the frequency that they were showing up in my feed. I promptly and without second thought deleted my alt accounts and deactivated my primary account in late October. Probably deleting that one soon too.
