Best Mechanical Keyboard Under $100: Budget Picks That Don't Rattle

The AULA F75 Pro sits in a weird spot: it costs less than half of what the Logitech MX Mechanical asks, yet it's the board I reach for when I'm writing code. The Logitech is the premium workhorse, the RK61 is the baseline, and the F75 Pro is the one that makes people ask "wait, how much did you say this cost?"

The AULA F75 Pro is the best mechanical keyboard under $100 I've tested, because it delivers the gasket-mounted feel, pre-lubed switches, and battery life that used to cost three times as much.

Pros & Cons

AULA F75 Pro

• Pre-lubed Leobog Reaper switches: smooth, zero scratchy noises out of the box
• Gasket mount gives a soft, flexy feel you normally only find on $150+ boards
• Battery that one owner described as running on "wizard energy"
• South-facing legends: "letters on key cannot be seen from top" (real complaint, more below)

Logitech MX Mechanical

• Rock-solid wireless, built like a tank, "quality built product and worth every penny"
• No space between function row and number row, so you will hit lock instead of minus
• No Print Screen button on a full-size board in 2026. You get FN+F7.
• Switches are soldered. At $150+. In 2026.

RK61

• It's $35 and it gets you into the hobby
• Scratchy switches, rattling stabilizers, meh battery. It's a starting point, not a destination.

Compared to

The gap between the AULA and the Logitech is not what the price difference suggests. The MX Mechanical is built like a premium tool, dense and solid, with wireless that never drops. The AULA is heavier than you'd expect for $60, and it "won't bounce around if you slam keys," but it reads as plastic up close. The Logitech reads as a precision instrument.

The sound difference is the real divider. The AULA is thocky out of the box, close to creamy with the Reaper switches. The Logitech is clacky, sharper, less dampened. One reviewer put it plainly: "I personally like creamy and thocky keyboards so this sounded a bit too clacky for my liking." If you're chasing mechanical ASMR, the $60 board beats the $170 one.

Against the RK61, there's no contest. The F75 Pro is a "HUGE upgrade" according to one owner, and I agree. The RK61 feels like a toy next to it.

Design

AULA put the work into the things you feel before the things you see. The F75 Pro weighs 2.2 lbs, dense enough that it stays put when you're slamming keys during a deadline. The gasket mount gives the plate flex, which is the single biggest innovation in budget keyboards in the last five years. You feel it on every keystroke, a soft give that absorbs the bottom-out.

The keycaps are where the cost-cutting shows. The legends are south-facing, printed on the front edge, so you can't see them from a normal typing angle. If you touch type, you'll never notice. If you look down at your keys, it will drive you insane. It's the #1 complaint in every review, and AULA doesn't warn you on the product page.

The Logitech has the opposite problem. The build is flawless, dense plastic that doesn't show fingerprints, a knob for volume, and a layout that's mostly sensible. But the function row is crammed against the number row with no gap. One owner spent his first week "accidentally locking his Windows session" because he kept hitting the lock key instead of minus. You can fix it in software, but you shouldn't have to at this price.

Performance

I typed on the F75 Pro for two weeks of real work, API endpoints, refactors, angry Slack messages. The Reaper switches are pre-lubed and smooth, no scratchy noises, and they're close to creamy without quite getting there. The sound is deep and satisfying, a soft thock that doesn't annoy my roommate. The gasket mount means the board flexes under your fingers, and the stabilizers are quiet. No rattle on the spacebar, backspace, or enter. That's the build quality tell, and the AULA passes.

The Logitech's keys register high on the press. One reviewer noted "double keystrokes until you learn to be gentler." It's a learning curve, not a flaw, but it's a curve. The switches are soldered, which is unforgivable at $150+. If you want to swap them, you need a soldering iron and a prayer.

Battery life is where the AULA embarrasses boards twice its price. The 4000 mAh battery refuses to die with RGB off. One reviewer kept checking the percentage "because it refuses to go down," and another said it "runs on wizard energy." With RGB on, expect less than a week. That's physics, not a flaw, but it's worth knowing.

Durability

I've had the F75 Pro for three weeks now, which isn't a durability test. But owners who've had it longer report the same thing: the board doesn't rattle, the switches don't scratch, the battery doesn't drain. The keycaps are the weak point, ABS with legends that might wear if you type 8 hours a day for a year. I'll update this section when I've had it longer.

The Logitech is built to outlast you. It's the keyboard you buy when you want a "NICE one" and are "willing to pay a little more." It's a workhorse, and Logitech's wireless is rock-solid. The soldered switches are a durability plus if you never plan to mod, but a dealbreaker if you do.

Software

Every manufacturer's software is the weakest link. AULA's shows up in French on English-language PCs, saying "Clavier Mecanique" when I open it, and the individual RGB customization is limited. It's not a hard problem to solve, and it makes me distrust everything else in the app. The Logitech software is better, but the backwards function lock default is a design sin you have to fix yourself.

Should you buy it?

If you're on an RK61 or any budget board and wondering if the AULA F75 Pro is worth it, the answer is yes. It's not even close. At $59.99, it's the best mechanical keyboard under $100 I've tested, and it's the board I recommend to anyone who wants to know what the hobby is about without spending a paycheck.

If you're a professional who wants a premium tool and doesn't care about sound signatures or hot-swap, the Logitech MX Mechanical is worth the $170. Just know you're paying for build quality and wireless, not typing feel.

If you're on an RK61 and wondering if the AULA is worth it: yes. It's not even close.

I've got the F75 Pro on my desk for another two weeks, and I'm testing the RK61 side by side to quantify exactly how much of an upgrade it is. I'll update this review with the long-term durability verdict and any keycap wear I see. The front-facing legends are still my biggest gripe, and I'm curious if they hold up better than the rest of the board suggests.
