24kupi Easy Study Watch V2 Review — Is the $55 Budget Watch Worth It?
The Easy Study Watch V2 is the cheapest device in 24kupi's watch lineup at $55. If you're on a tight student budget and thinking about a cheating watch, this is probably the one you're considering. I bought it alongside the Invisible Watch ($70) to compare them directly.
What You Get
The V2 is a small rectangular device with a monochrome LCD screen, a silicone wrist strap, and a 3.5mm USB charging cable. Like the Invisible Watch, it's not actually a watch — it doesn't tell time. It's purely a text display device designed to sit under your sleeve.
Screen Comparison: V2 vs Invisible Watch
The V2's screen is noticeably smaller than the Invisible Watch — about 0.7 inches vs 0.9 inches. The V2 uses a basic monochrome LCD (grey text on greenish background) while the Invisible Watch uses OLED (white text on black). The OLED is significantly easier to read, especially in dim lighting.
On the V2, you can fit about 3-4 lines of text at a readable size. Scrolling works the same way — side buttons. But the smaller screen means more scrolling to find what you need, which means more time staring at your wrist, which means higher detection risk.
Build Quality
At $55, you get what you pay for. The plastic body feels flimsy. The strap is thin silicone that stretches out after a few uses. The buttons have a mushy, imprecise feel. It works, but it doesn't feel like a $55 device — more like a $15 gadget from AliExpress with a markup.
Loading Notes
Same process as all 24kupi products — connect via included cable, drag text files. Storage capacity is adequate for any exam. The V2 handles plain text files only — no images, no formatted text.
Battery Life
About 2-2.5 hours of screen-on time. This is shorter than the Invisible Watch (3 hours) and might be tight for longer exams. If your exam is 3 hours, the V2 might die before you finish. Charges via the included 3.5mm cable — takes about an hour to full charge.
Detection Risk
Same issues as the Invisible Watch — wrist-based devices are the first thing proctors check in 2026. The V2's smaller size is marginally less visible under a sleeve, but the difference is negligible. If a proctor is checking wrists, they'll find either device.
V2 ($55) vs Invisible Watch ($70) — Which One?
If you're choosing between these two, spend the extra $15 and get the Invisible Watch. The OLED screen is dramatically better, the battery lasts longer, and the build quality is slightly higher. The V2's only advantage is saving $15, which isn't worth the downgrade in screen quality and battery life.
Pros
- Cheapest device in 24kupi's lineup ($55)
- Small and lightweight
- Simple to load and use
- No partner needed
Cons
- Screen is very small and hard to read (monochrome LCD)
- Short battery life (2-2.5 hours)
- Cheap build quality
- Wrist devices are heavily scrutinized by proctors in 2026
- Only displays pre-loaded text — no internet, no AI
- The Invisible Watch is only $15 more and significantly better
Final Verdict: 3/10
The Easy Study Watch V2 is the worst value in the 24kupi catalog. For $55, you get a tiny, dim screen with short battery life in a form factor that teachers actively look for. Spend $15 more on the Invisible Watch if you must have a wrist device, or $44 more on the Magic Calculator V3 which has a bigger screen and doesn't go on your wrist.
