What product most improved your quality of life?

A good bed. There is no bed like my own. I have a good night's rest so I can fully take the next day again.

I was doubting to write the next one. Since it's obviously not a "product", but want to mention anyway.

My wife. She really completed me in such a way that it significantly improved my quality of life. She holds the mirror in front of me at the right times and works in an entirely different field, making her a great sparring partner.

It's hard to pick just one.

* Laser eye surgery in 2009 - I know it isn't really a "product", but it is one of the best purchasing decisions I've made.

* Kindle - it is so much more convenient than reading or collecting physical books, and with the e-ink screen doesn't detract from that "book feel" for me

* Tretinoin - this might be a weird one, but as someone who is very into skincare this single product makes me feel confident that I am effectively taking care of my skin for the long term. I don't have to worry about if I'm "doing it right", or bother with gimmicky expensive "texture-enhancing" or "anti-ageing" or whatever-the-next-buzzword-is products. Tretinoin has a very large body of research behind it. We know it works. A single tube of tretinoin (coupled with sunscreen!) saves me a lot of wondering and money. This is not to say I use nothing else at all, it's more like this one product and the knowledge base we have on it keeps me from spending money on otherwise expensive skincare that I don't need, which is _marketed_ to do the same thing as tretinoin but isn't actually shown to work like tretinoin is.

Nice glasses. There are a lot of bad ones out there that I've been wearing for over 10 years.

The bad ones DoS my brain with pointless information, greatly harmed my focus and ability to think, as well as gaming abilities. It's also made driving, especially in heavy rain, difficult and hazardous.

The good one made life seem really high resolution. It reduces eye strain a lot, which is wonderful when you work with computers a lot and live in a sunny area.

Peak Design messenger - solved all things bags in my life. Proud of having it on me all the time, beautiful and functional.

Sennheiser PXC-550 - One of the best wireless headphones out there. I can keep them on 8 hours a day without any stress.

Keychron K2, just a well-thought wireless/wired mechianical keyboard. Less fatigue and more confort, I can type 4x more text now.

I've been using these every single day for years now.

MacBook - Spent years developing software on windows/xterms, my company finally approved Mac for work.

Safari Online - Getting learning material has never been so easy. Actually learning all of them is different :)

AWS - I can get hardware resource without lengthy PO and approval.

Wireless Headphone - Apple Airpod.

A fully stocked and well equiped kitchen in the apartment

* My exercise bike - I have no reason not to get in some physical activity (rain, time, etc.).

* My desk whiteboard - It helps so much when confirming/working out a solution.

* My wireless mouse and keyboard - They fit my hands and I can put them away when the whiteboard is what I need.

A membership in the car sharing company Car2Go. It was amazing being able to be my own taxi driver and then drop off the car. Too bad it'll be leaving my home area soon.

Wireless headphones. Bar none. The fact I can walk around my apartment and listen to a {book,podcast,song}, without worrying about cables or carrying my phone, has been amazing.
