Lefon F35 Vertical Mouse Review: Ergonomic for Under $20?

The problem that started this

If you spend more than five hours a day at a desk, you probably know the feeling - that low-grade ache building in your wrist or forearm by late afternoon. I started looking into vertical ergonomic mice after ignoring that feeling for longer than I should have. The well-known options from Logitech and Microsoft start around $40 to $60 for the entry-level models. Then I found the Lefon F35 sitting at about $20. My first instinct was to move on. My second instinct was to actually research it.

Honest review: what I found

The Lefon F35 is a wireless vertical ergonomic mouse with a 2400 DPI optical sensor, USB-C charging, a 2.4GHz wireless connection, and an optional blue LED. It works across Windows, Mac, and iOS. What genuinely surprised me was the build quality at this price. The surface has a soft rubberized coating that feels smooth and grippy at the same time - a few buyers specifically called it out as feeling good in hand, and I get why. The main click buttons are satisfying and crisp, not mushy. The vertical grip positions your hand in a more natural handshake orientation, which does reduce the rotation stress on your wrist and forearm compared to a flat mouse. After an adjustment period of a couple of days, it starts to feel normal. The USB-C charging is a genuine practical upgrade over mice that run on AA batteries. You charge it when needed and move on. Battery life appears solid based on user reports - no one is complaining about running dry mid-session. The LED is a nice optional extra. Three modes: on with light, on without light, off. Harmless and kind of fun if you have a lit-up desk setup. Now for the honest limitation worth noting upfront: the scroll wheel. Multiple buyers and my own assessment suggest it requires slightly more force than feels natural. For occasional scrolling, it is fine. If scrolling is a constant and heavy part of how you work - think reading long documents or browsing endlessly - the stiffer wheel may become irritating over time. That is the real trade-off at this price point.

What would you normally get at this price?

At around $20, your typical options are basic wired or wireless flat mice with no ergonomic consideration whatsoever. The budget vertical mouse category is small and usually costs more. Anker's entry vertical mouse runs $25 to $35. Logitech's MX Vertical starts at around $80. The Lefon F35 sits in a gap that barely exists - it is the rare option that gives you the vertical format with USB-C charging and a decent surface feel without crossing into the $40 range. It is not a precision gaming mouse. The 2400 DPI is functional but not extraordinary. If you need a mouse for serious gaming, look elsewhere. But for office work, writing, casual use, or anyone wanting to test whether vertical mice actually help their wrist without committing serious money, it lands in a useful spot.

Buy it if... / Skip it if...

Buy it if: you are experiencing wrist fatigue from long desktop sessions and want to try the ergonomic vertical format without spending $60 or more. Also a good pick if you hate swapping batteries and want a clean USB-C solution. Skip it if: you are a competitive gamer who needs a high-precision sensor and fast response times. Or if heavy scrolling is a core part of your daily workflow and a stiffer scroll wheel would frustrate you from day one. My honest take: the Lefon F35 is a sensible buy at around $20 for anyone dealing with wrist discomfort at the desk. It does the ergonomic job it promises, the build quality punches a little above its weight, and USB-C charging is the right call. The scroll wheel is a real drawback - just go in knowing that. For the price, I would not have expected this level of overall quality. Check current pricing here: https://www.ali-ex.com/uYY0ze
