The vacuum sealer reminds me: a handheld electric pump.

Some are strong enough to blow up car tires. Especially if you have kids, they’re great for inflating water toys and balls and whatnot.

Second the warm white Christmas lights.

They can quickly make a depressing apartment feel like a warm home.

LAN tester.

I thought of it as fancy electrician / network equipment. Not anymore. Now it’s basic troubleshooting / procedure.

On a particularly frustrating switch installation, I picked one up for like $20 on Amazon, and it’s made me much less annoyed by network changes.

For context, I’m one of those people who hoards any electronic bits that might prove useful on a hobby project later, so lots of old patch cables and cable reels with unknown breaks, so maybe a LAN tester is really only worth it for others like that, but I’d recommend it to any level of tech enthusiast at least.
