What's something $100 or less but is a total game changer?

Honestly, pick up a decent headlamp. Not the cheap ones that flicker out after a week, but a solid, rechargeable one with at least 500 lumens. I keep one in my truck and one in the kitchen drawer, and it’s saved me so much frustration when I’m trying to fix something in a dark corner or when the power cuts out. Having both hands free while you’re actually seeing what you're doing is a total life saver.

Another thing that changed my life for under a hundred bucks is a high-quality insulated tumbler or bottle. I know it sounds basic, but when you're out and about all day, having ice water stay frozen for 24 hours straight or coffee stay hot until the afternoon is a massive luxury. It sounds like a small thing, but once you start using a good one, you’ll never go back to those cheap plastic ones that sweat all over your stuff.

If you do a lot of stuff around the house, grab a good impact driver set if you can find one on sale, or even just a set of high-quality magnetic bits. Most people struggle with stripped screws because they use the wrong gear, but having the right bits makes everything so much faster and less annoying. It’s one of those things you don't think about until you actually have it, and then you wonder how you ever managed without it.
