$30 bidet from Amazon.

Toothbrush

Small whiteboard to track stuff like the grocery list or reminders. When I want to go shopping, I'll snap a picture of the list before I go out.

One of those percussive massage guns. Holy fuck, if you have any tension from anxiety, sore muscles, even headaches, it'll work wonders.

Ear protection

The wireless charging pads for phones are game changers, I have spent so much time fiddling with charging ports that have gotten worn out, sticking pieces of paper underneath them so it actually connects etc. The only time they aren't ideal is when you're trying to use your phone in bed while it's charging.

USB rechargeable hand warmer/battery bank. Is a good hand warmer and came in very handy to recharge phones during a power outage.

Similarly, CAT "3 in 1" portable power station. Jump starts cars, pumps flat tires, has AC and USB input to charge items. Also have a book-sized lithium battery jump start pack which is great. Both have saved my ass a few times.

Robot vacuum (Wyze). It does a good job vacuuming and not running into stuff

Milwaukee electric ratchet. I do a ton of work on cars and that is my favorite tool. It was expensive, but it's more than paid for itself. I use it so much all of the red bits are pitch black. Ive had it 6 years now and the battery still holds a charge for 8 hours of work. It holds up to all abuse and fits almost anywhere. I use it with hex head sockets to assemble furniture too.

You can get a secondhand Pebble 2 smartwatch for something like $50 or less these days, and even though they are a few years old they still work great with a few software tweaks (s/o to Rebble).

If you've ever thought a smartwatch would be helpful, it's a great way to get started, and they are pretty hackable (not quite as open and hackable as some projects out there, but a lot more polished and put together than most OSS smartwatches).

Really, the only stuff you are missing out on compared to the expensive new ones is calling from the watch (weird), music/videos on the watch (why), and location tracking if you're a runner or something and don't want to take your phone with you. But for me, easily glance-able notifications is the real best part, and the pebbles do that better than most of the new ones. Not to mention the battery lasts a solid week of heavy use at least, compared to <1 day for the fancy new ones.

A bluetooth sleep mask. I am on my third one in about 4 years and it has saved me from lifelong sleep related stress. I am on round three of Discworld right now and love how I can use that to get my mind to stfu.

literally a $2 egg timer I keep on my desk to use instead of fishing out my phone to set short timers

Manual food processor. Cost me less than £10, uses a ripcord to chop stuff up in a little bowl. Onions and garlics now take no time at all, and if I want I can make them super fine for soups and such.

DE safety razor: I bought one years ago and I STILL haven't needed to order my first set of blade refills yet. With a better AND cheaper shave every time that's more environmentally friendly thanks to not being made of plastic and minimal waste, I can say that disposable razors are the 8th form of liberalism:

This is the one I use that I got on sale. Other options include Edwin Jagger and Merkur.

I got an electric toothbrush last year, and my plaque buildup is way less than it used to be.

Shoe horn and stretchy shoe laces. I didn’t realize how much I was ruining the back of my shoes by slipping them on until I got this combo. I tie my shoes nice and tight one time and my shoes last longer now.

I used to be really overwhelmed by pet hair, but we got these specific lint rollers... They look like a slim vacuum head kinda. They have inside them those red glossy one-way brushes, the kind that usually come in a kind of rectangle that you sweep over your clothes one way and then manually de-lint by pushing the opposite way.

Except these have just thin strips of those brushes and a chamber to deposit the hair. You swipe it back and forth like a paint roller and it grabs all the hair both ways and clears shit up extremely quickly.

Cannot live without it

Edit: like let em emphasize that it is probably 10 times faster than a normal lint brush, and three times faster than a fucking adhesive roller

If you are not aware of a cuticle nipper it is ten thousand times better at hangnails than nail clippers

A couple years ago I was doing something where I needed to wear dress clothes and had no room for my wallet, so i took a bulldog clip and put my cards/id/little bit of cash in it.

I never put them back in the wallet, it was such a game changer. No longer did I have to take my wallet out of my back pocket every time I sat down or fear back pain.

Motion sensor light switches. I like walking into a room and the lights just turning on.

You gotta get one of these.
