The TECKNET Ergonomic Mouse is a wireless vertical mouse designed for users who experience wrist or forearm strain during long PC sessions. Its signature 57° ergonomic angle promotes a natural wrist posture, reducing pressure on the carpal tunnel compared to traditional flat mice. This mouse supports three connection modes — Bluetooth 5.3, Bluetooth 3.0, and 2.4GHz via the included USB-A receiver — and can switch between up to three paired devices with a single click. The optical sensor offers six DPI levels from 800 to 4800, making it suitable for office work, creative tasks, and everyday browsing. A built-in rechargeable battery provides up to three months of use on a 1.5–2 hour charge, eliminating the need for disposable batteries. Connection modes: Bluetooth 5.3, Bluetooth 3.0, 2.4GHz (USB-A receiver) Multi-device support: up to 3 devices, one-click switching Compatible OS: Windows, macOS, Chrome OS, Linux (side buttons not supported on macOS) The USB-A receiver works with most laptops and desktop PCs. For Bluetooth-only devices like tablets or phones, simply pair via the Bluetooth menu without needing the receiver. Check the retailer's page for the latest price. Office workers with long desk hours: If you spend 8+ hours daily at a computer, the vertical grip reduces wrist strain, and the silent clicks keep your colleagues undisturbed. Multi-device users: Ideal for those juggling a laptop, desktop, and tablet. Switching between devices is instant, so you can move from typing on a PC to browsing on a tablet without re-pairing. You stay focused without annoying those around you. Not ideal for: Competitive gamers needing high polling rates and extra buttons, or macOS users who rely on side buttons — those features are limited here. Side buttons do not work on macOS. Windows users get full functionality, so plan your OS accordingly. The 2.4GHz receiver is USB-A only. If your laptop has only USB-C ports, you will need a USB-C to USB-A adapter. The charging cable is relatively short. While you can use the mouse while charging, the cable length may feel restrictive depending on your desk layout. Users with larger hands may find the mouse slightly small. If possible, try the size in person before purchasing, especially if you have above-average hand size. Q: Can I use this mouse for gaming? A: It works for casual games like browser titles or RTS, but for fast-paced FPS or competitive gaming, a wired gaming mouse or a high-performance wireless model would be a better choice. The DPI goes up to 4800, but the polling rate and response time are not optimized for gaming. Q: How long does the battery last? A: TECKNET claims up to 3 months with 2 hours of daily use. In real-world heavy use (8 hours/day, 5 days/week), expect around 1 month or more. A low-battery LED indicator flashes when it is time to recharge, so you will not be caught off guard. Q: Is this mouse suitable for left-handed users? A: No, this is a right-hand-only design. Left-handed users will find the button layout awkward. Look for an ambidextrous or left-hand-specific ergonomic mouse instead. ### Product Disclosure (Amazon) - Manufacturer: TeckNet - Seller: soragadgetshop - Fulfilled by: soragadgetshop - ASIN: B0G5P4K1G6 - Note: This article covers a manufacturer-made product based on Amazon listing details.
