Ask HN: What tech purchase did you regret even though reviews were great?

Mysa thermostats - don't integrate well with Home Assistant and can't even reliably follow schedule. Every Samsung phone I've ever owned - great hardware, but the software is a mess, especially with all of the Samsung apps that duplicate the Google apps. Sony smart TV - was excited about running Android TV apps, but the onboard hardware is so bad that everything lags, and I actually ran out of space after installing 10-20 apps (it only has 4GB of flash storage). Also, its Ethernet adapter has a hardware bug that occasionally freezes up my entire network by spamming it with flow control frames. Any home tech gadgets. Robot vacuums, smart lights, smart thermostats, internet connected TVs and appliances, most kitchen gadgets especially if they require power. None of it lives up to the hype and it's all e-waste in a couple of years if not sooner. Can't speak to most of those but smart lights are pretty nice. I made sure to buy zigbee ones so that I'm just tied to home assistant which even if it goes out of business will still work with whatever binaries I've downloaded already (as well as it works locally so I can control them during internet outages). I'm sure somebody else can explain why you should get Thread or Matter nowendays but I never bothered to learn the differences. But yeah, the average life of a company is what 1 year? Don't get any product you want for more than 5 years from a company younger than 5 years if you need that company to exist for it to work. Nest started out great for me as an early adopter. The recent iterations are just frustrating. The apps are laggy. It’s always prompting me to join an energy savings program no matter how many times I say no. We had to disable the home/away detection because it went from working well to thinking we were away 5 times per day. Nest stands as my example of a product that went from great to terrible through complete mismanagement and customer neglect. Yep. I have an Ecobee currently and have had a Nest previously. Am totally perplexed why people like these things. Just opened the Ecobee app and literally at the top is an ad saying "The Holiday sale is here. Shop now." Irritates me to no end. I cannot agree more. The battery not even lasting a day is what prevents me from using it. When I want to go for a run with it, it's always out of battery. I had this exact problem with my Apple Watch. My family got me an Ultra as a gift, and I really didn't think I was going to use it (I didn't even want it), but it ended up being a total gamechanger, and now the Ultra is my favorite gadget and a huge motivator to get into better shape. I got a Garmin watch after being frustrated with the tech company watches lasting only...
