Bidet.

Yeah. I said it.

Blackout curtains in combination with a sunlight alarm clock to fall asleep more easily and wake up gentler without my phone.

LSD

A Game Genie

Noise canceling headphones. Yes, they exist for under $100, maybe not the best, but they’re a godsend.

Bidet attachment for your toilet bowl. Trust me, you’ll never go back.

a high quality pocket knife. never leave home without one.

Multitool. Can't live without.

Eyeing a rice cooker, it's really not a need-to-have but I might go for it... Edit: went for it and got one from my local asia market. :)

A microwave sandwich griller. I saw one recommended on another of this type thread, so I gave it a try. You can’t believe how great this thing is. When I worked in an office, I had grilled sandwiches several times a week, and I still use it at home all the time.

• Bidet
• Hand barbells + weights
• Inexpensive watch like a casio f-91w, or a cheaper smart one. Turning off all phone sound notifs is nice.
• Used e-reader
• Heated blanket
• One of those water bottles with a straw and a smart lid

Shower curtain with pockets. Never again will you knock bottles off of those inadequate shelves.

You really should buy a bedbug proof mattress cover and interceptors for the legs of your bed and furniture. Trust me when I say that an ounce of prevention will save you a lot of trouble, cost, and emotional trauma. Even if it costs more, buy then anyway.

Low-profile noise-cancelling earbuds. Lived with a snoring roommate for some months, don't know how I would've slept without those.

House slippers.

Cast Iron Skillet, take care of it and you will pass it down to your children.

As someone that works from home and eats a lot of sandwiches; a bread maker. Great for pizza dough too!

Electric kettle.

Bone conduction headphones.

Rechargeable head lamp.

Nice EDC knife.

Driving gloves.

A really good insulated cup.

French press.

Digital kitchen scale.

Slow cooker.

A Time Timer.

They're not cheap, especially for a timer that's bare bones (~20 USD).

But it has changed my work life.

1. People who want to interrupt me while I'm working can now see how long until I have my next break. So I am interrupted less.
2. Now I self-regulate a bit better, so I'm able to work longer without destroying myself in the process. I take breaks that help me with repetitive strain injuries and with feeling like I'm a human being and not just a machine.
3. Now I remember to actually start timers when I start working. I know this is a bit silly, but I was having trouble creating a habit of stopping for breaks. I tried to solve this by setting timers on my phone, but I constantly forgot doing it. Now I'm reminded to start a timer by something that I see on my desk.

I was gonna say an OLED monitor but then i saw the 100$ or less

One of those flip boards for folding shirts, especially if you’re adhd, it makes it so you can neatly fold them and still see the front of the shirt so no more unfolding a bunch of things to check if it’s what you want and then just get left there unfolded

Flex Reusable Disc

For me, literally game changing item is a game controller. For the games with native controller support it is awesome. Its easier and more confortable than mouse and keyboard. Of course it is not comparable with mouse and keyboard, especially in games heavily relied on mouse, but for anything else, on my opinion, it is a better option. My controller is quite cheap, but works well. I bought a controller to see what it is and how different it is for gaming, compared to mouse and keyboard. At first it was difficult, as i did not have an experience with controller, but now i enjoy it.
