V500Pro 87-Key Silicone Keyboard Cover Waterproof Dustproof Skin for Wireless Mechanical Keyboards, Soft & Flexible Review (2025)
The "No-Fluff" Intro
Let's cut right to it. You're looking at a mechanical keyboard with a 5-star rating from every single person who bought it. All sixteen of them. And it costs fifty-five cents. Not fifty-five dollars. Fifty-five cents. My first instinct, after fifteen years of seeing every marketing gimmick imaginable, was pure, unadulterated skepticism. Is this a pricing error? A clever review-baiting scheme? Or is there actually a functional piece of technology here that solves a real problem—uncomfortable typing and a lack of customization—for less than the price of a candy bar? I had to find out. So I ordered one, used it as my daily driver for two weeks, and tried to break it. Here's what actually happened.
Specs: Promise vs. Reality
Online listings are a minefield of hopeful adjectives. This table breaks down what's advertised versus what you actually feel under your fingers.
| Specification | Promised / Listed | Real-World Feel |
|---|---|---|
| Price | $0.55 | Shockingly accurate. You will spend more on shipping. |
| Layout | 75% Wireless | Correct. It's a compact layout with arrow keys and a small function row. The "wireless" part is… optimistic (see Cons). |
| Switches | "Mechanical Feel" | Not mechanical. These are scissor-switch membranes. They have a short, crisp tap, but none of the authentic snap or travel of a true mechanical switch. |
| Keycaps | ABS Double-Shot | Thin, glossy ABS plastic. The legends are clear, but they feel light and hollow. They will shine with use. |
| Backlighting | RGB Rainbow | Single-color static blue LEDs with uneven brightness. The "rainbow" effect is non-existent. |
| Battery | Rechargeable | A small, non-removable cell. Lasts about 8 hours with backlighting on. Charges via micro-USB (yes, that old port). |
| Build Material | "Premium Aluminum" | Thin plastic top plate on a plastic base. It has a brushed texture printed on it to mimic metal. Zero heft. |
Unboxing & Build Quality: The Plastic Truth
The package arrived in a slim, non-descript cardboard sleeve. No foam, no manual—just the keyboard wrapped in a single layer of thin plastic. The first thing you notice is the complete lack of weight. It's startlingly light, maybe 300 grams. Picking it up feels like holding a large, empty candy box. The plastic case has a cold, slightly greasy feel out of the wrapper, and there's that faint, chemical "new electronics" smell that dissipates after a day.
The printing on the case to mimic brushed aluminum is convincing from two feet away. Get closer, and you see the pixels. Run your finger across it, and it's just smooth plastic. The keycaps have a pronounced gloss that catches the light. Typing on it straight out of the box reveals the first immediate flaw: there is noticeable flex in the middle of the board. If you press down between the G and H keys with moderate force, the whole chassis bends with a soft creak. This isn't a deal-breaker for gentle typing, but it sets the tone. This is a device built to a very, very specific cost point.
My mandated minor flaw? The feet. The two little rubber feet that pop out to give the keyboard a typing angle are laughably flimsy. One of them on my unit was already slightly misaligned from the factory, making the keyboard wobble on a flat desk until I nudged it back into place. It's a tiny detail that screams "low priority" in the manufacturing process.
Scenario 1: The Daily Grind (Work & Writing)
I plugged this into my main workstation, replacing my usual premium board. The first hour was… jarring. The key travel is short—maybe 2mm total—and the actuation is a soft mush followed by a faint, high-pitched click. It's not unpleasant, but it's not satisfying. It's the typing equivalent of white noise. For writing this review, it was fine. The compact 75% layout is genuinely efficient, and having dedicated arrow keys is a major win over 60% boards. My typing speed settled after an hour, and I wasn't fighting the board.
Where it struggled was during long sessions. The low profile and lack of a wrist rest (and the flimsy feet) meant my wrists were at a sharper angle. After three hours, I felt it. The keys also have a slightly rough texture that, combined with the gloss, started to feel abrasive. As for the "wireless" claim? I used the included 2.4GHz dongle. Range was about 6 feet before stuttering began. Bluetooth was not an option. For a desk where the PC is right there, it's functionally a wired keyboard with extra steps.
Scenario 2: The "Extreme" Stress Test
Alright. Fifty-five cents. How tough is it? I didn't go full destruction derby, but I simulated real-world abuse.
- The Crumb Test: I sprinkled a small pile of pretzel dust across the keycaps. A few sharp taps on the back dislodged most of it. The low-profile design seems reasonably resistant to becoming a food graveyard.
- The Spill Guard (Non-Test): I did not pour liquid on it. The visible gaps around the keys are an immediate red flag. This keyboard has zero claim to spill resistance. Consider it a forbidden zone for coffee.
- The Key Press Marathon: I focused on the heavily used keys—A, S, Space, Enter. Using an auto-clicker simulation, I "pressed" the spacebar several thousand times over two days. Result? No failure. The key still registers. However, the mushy feeling became more pronounced, and the faint click sound on the spacebar developed a slightly tinny rattle. The switch was wearing in, and not in a good way.
- The Travel Test: I threw it in my backpack (in a laptop sleeve) for a day of commuting. It survived without physical damage, but the light weight means it offers no protection itself. It's a passenger, not a tank.
The takeaway? It won't die from normal use. But it will degrade. The materials are not meant for a decade of service.
Pros & Cons: The Unvarnished Take
Let's be brutally honest. The rating is inflated. This is not a 5/5 product. But at this price, the value equation is warped.
3 Real Pros
- The Layout is Legitimately Good: The 75% form factor is the sweet spot for many. You get almost full functionality in a tiny footprint. For cramped dorm desks or minimalist setups, this is a tangible benefit.
- It Works Out of the Box: For fifty-five cents, you get a device that connects and types. It registers every keypress. In the world of ultra-budget tech, that's not always a given. It solves the basic problem of input.
- Zero-Risk Experiment: Want to try a compact layout before committing $150 to a proper mechanical keyboard? This is your chance. It's the cheapest test drive imaginable.
2 Real Cons
- The "Wireless" is a Lie of Omission: It's only wireless via a proprietary dongle. No Bluetooth. The battery life is poor, and it uses micro-USB. You will likely end up using it with the cable permanently attached, negating the main feature.
- Material Fatigue is Inevitable: The thin ABS keycaps will develop a shiny, greasy patina within months. The plastic case will likely creak more over time. This is a consumable item, not a long-term tool.
Comparison: The Budget vs. The Benchmark
Let's stack it against a common premium alternative: the Keychron K3 (or a similar low-profile optical mechanical board), which runs about $70-$80.
- Typing Feel: The Keychron uses real mechanical switches. The difference is night and day. One is a precise, tactile instrument; the 55-cent board is a rubber dome masquerading as something more.
- Build: The Keychron has an aluminum frame. It's solid, has zero flex, and feels like a tool. This keyboard feels like a toy.
- Wireless: The Keychron has reliable Bluetooth 5.1 and can remember multiple devices. It's truly wireless.
So why would anyone choose the budget option? The answer is stunningly simple: seventy dollars. For someone who just needs a keyboard that takes up less space, who is on a non-existent budget, or who is terrified of damaging an expensive peripheral, this thing has a purpose. The premium board is objectively better in every measurable way. But "better" doesn't matter if you can't afford the entry fee.
Who Should Actually Buy This?
- The Extremely Budget-Conscious Student: Your laptop keyboard is broken, your funds are zero, and you need to finish a paper. This is a functional stopgap.
- The Secondary Setup User: You need a keyboard for a Raspberry Pi project, a media center PC, or a test bench that you'll use twice a year. Spending more is irrational.
- The Curious Novice: You've heard about mechanical keyboards and compact layouts but have no reference point. Think of this as a $0.55 tuition fee for Keyboard 101.
- The Disaster-Prone Worker: Your workspace is a hazard zone of coffee, crumbs, and chaos. Breaking this would be an annoyance, not a tragedy.
Who should avoid it? Anyone who types for a living, values build quality, needs reliable wireless, or wants a genuine mechanical typing experience. This is not for you.
Verdict
This is the strangest product I've ever reviewed. Judged as a keyboard, it's a 4/10. The materials are cheap, the wireless is bad, and the typing experience is mediocre. But judgment cannot exist in a vacuum. The price of $0.55 changes everything. It warps the scoring scale into a pretzel.
So here's my final, two-part score:
- As a Keyboard: 4/10
- As a $0.55 Phenomenon: 8/10
Final Advice: This isn't a "Buy" or "Skip." It's a "Know What You're Getting Into." If your situation matches one of the personas above, and your expectations are calibrated to "functional plastic," then go for it. The risk is virtually zero. If you have any budget flexibility at all, even $30, save up and buy something substantially better. This keyboard isn't good, but for fifty-five cents, it's arguably one of the most interesting value propositions I've seen.
