For me, it’s an electric toothbrush. It doesn’t matter if you go with Sonicare or Oral-B, once you start using an electric toothbrush, regular toothbrushes don’t ever feel like they clean your teeth properly. The smooth plaque-free top layer of your teeth that you can feel after using an electric toothbrush can’t be replicated with a regular toothbrush.
Cordless drill. I was a die hard corded guy but then I tried a friend’s one during a big move. Went out and bought one the next day.
I also agree, but to take it further, I decided I’d had enough of cables on my circular saw. Got a small, lightweight one, and omg, it’s SO good.
I really don’t like the proprietary batteries each company use for their cordless tools though. I don’t want to be locked into 1 company and I don’t want to buy 8 different batteries.
While I agree that vendor lock in sucks, getting a universal standard open source tool battery is not likely to happen. I decided to go with the Milwaukee M18. They have a huge variety of tools available, and they all use the same interchangeable battery. I have a drill, an impact driver, a circular saw, and hedge trimmers.
I wanted to punch someone when i realized my Bosch drill and Bosch electric saw use different batteries. They’re identical in size, but the plug part on one is a mirror image of the other and so not interchangeable
I also recommend a cordless impact driver. The amount of torque you can generate with a drill is limited by your ability to hold the drill. The amount of torque you can generate with an impact driver is magnitudes more. Great for driving screws, tightening nuts, I’ve even used it for drilling through wood with a spade bit.
But not your only drill.
To be fair, the early ones were pretty crappy compared to what they have now.
At the start, you really couldn’t use it for real work. The convenience came at a huge cost.
These days all but the most extreme tasks can be done with cordless.
