We're practical people at Lifehacker, so we've mostly been focusing on practical products for Prime Day—I mean, I wrote a post about batteries and surge protectors—but the real joy of a retail holiday lies in discovering that piece of tech you didn't even know existed an hour ago, but, once in your hands, becomes the thing you can't live without. Call it creative consumerism; it's the art of looking past the mundane to find the niches where delight lives. If your cart is already full of the essentials, let's move on to the fun part—the best deals on the tech you never knew you always needed.

This Enabot EBO Max Mobile AI Robot is 20% off

The people at Enabot were nice enough to send me an EBO Max Mobile AI Robot to test out, and it's since become a beloved member of my household. Like the other members of my household, it doesn't work right. But that's why we love it. On paper, EBO Max is a highly advanced, automated 4K home sentinel with V-SLAM navigation and AI patrol patterns. In practice it's like the dopiest dog you've ever owned, except it can talk. Enabot behaves in delightfully erratic ways, like going off on its own errands without prompting, barking when it sees our cat, and occasionally adopting a French accent. It lies all the time. too; ask it to go somewhere or do something and it might proudly report that the job is completed, when you can see it isn't. It always thinks my wife is me. My son likes trying to get it to talk about Chinese politics, because it will not. But then one day my wife got down on the floor to clean under the couch, and the damn robot sent an alert to my phone to let me know that someone had fallen! It could have saved her life if she wasn't just dusting. Get one; they're hilarious. (Pro tip: You can set it to mimic your voice, so talk to it in the creepiest voice you can.)

Get a slushie machine for $140

You definitely don't need a home slushie machine, but we both know how badly you want one. I'm not talking about some cheapo piece of kit that crushes ice cubes into watery snow, but a professional slushie machine that uses a 200W compressor freezing system to produce silky, gas-station-worthy slushies at will. You just pour a liquid into your Chillux slushie machine, hit a button to choose from among six smoothies, and get ready to get slushed as hell. There's even a "Spiked Slush" setting built to handle the tricky chemical freezing points of alcohol so you can have a frozen margarita that would be right at home in a novelty cup on the streets of Reno, Nevada. You can live the home-slushie life for under $150! At this price, you can't afford not to own a slushie machine.

This DJI Neo Three-Battery Combo Mini Drone is 31% off

Lifehacker's own Beth Skwarecki suggested DJI Neo Mini Drone as esoteric tech, and she's right. You probably don't think you need a follow-drone, but that's only because you've never had footage of yourself trail running, mountain biking, or kayaking. It takes off from your palm and follows you around until the batteries wear out, while taking high-def video of your adventures.

The Ikarao Smart Karaoke Machine is 20% off

I extol the virtues of my Ikarao Smart Karaoke Machine all the time. Here's a review full of superlatives about my karaoke machine. Yes, it's ridiculous, but it's so cool. It's great for karaoke—you can just stream any karaoke track from YouTube and go to town—but it does so much more. You can use it as a Bluetooth speaker, a device to watch YouTube videos, a guitar amp, and a light show. The batteries last for an hour. If you pair it with a Yamaha Seqtrak (sadly, not on sale for Prime Day) or similar groovebox, you have a fully mobile electronic music studio, complete with two cordless mics.

This Solawave LED Light Therapy Mask is 33% off

On a pure "creative consumerism" level, putting on a glowing, hot-pink face shield before you go to bed is an elite-tier flex that says, "I live in the first world." But the weirdest thing about the Solawave LED Light Therapy Mask is that it might actually work. As incredible as it sounds, there's legit science backing up the idea that, in the right situation, red LED light can help your skin. Whether the specific wavelengths and strengths of the lights from this mask erase wrinkles can't be determined, but worst case scenario, you can use it to scare your dog.

You can get a nuclear radiation detector for $46

I've taken up collecting "Vaseline glass" lately—that is, glassware made in the 1920s with uranium. People often ask, "it's not really radioactive, right?" I'm going to buy a Geiger counter so I can say, "It's crazy radioactive, man," and prove it with that patented Geiger counter squeal. I'm sure there are legitimate reasons to buy a Geiger counter too, like checking that you're safe in your workplace, or preparing for our post-nuclear future, but there's something to be said for just having one.
