The BenQ ZOWIE EC2-DW is a wireless gaming mouse that continues BenQ ZOWIE's EC lineup of right-handed gaming mice. It's the follow-up to the EC2-CW, and improves upon it with a new PixArt PAW3950 sensor, a higher maximum polling rate of 4000Hz, virgin-grade PTFE mouse feet, and a lighter shell while keeping the shape unchanged. This mouse is the medium-size option, but it's also available in large and small size variants.
Our Verdict
The BenQ ZOWIE EC2-DW is adequate for office work. It has great build quality and a comfortable right-handed shape available in three different sizes. While you can connect it to two devices simultaneously using its two included USB receivers, it lacks Bluetooth support. Also, there isn't any customization software for reprogramming buttons, and the scroll wheel lacks L/R tilt inputs and a free-scrolling mode.

Differences Between Sizes And Variants
The BenQ ZOWIE EC2-DW is only available in a black colorway. This mouse is part of a wider lineup of EC-DW Series, which are wireless iterations of BenQ Zowie's original EC Series mice, and an update to the EC-CW series. This mouse is available in three different sizes.
| Name | Size |
|---|---|
| EC3-DW | Small |
| EC2-DW | Medium |
| EC1-DW | Large |
We bought and tested the Medium-sized EC2-DW, but we expect the results of our tests to broadly apply to all three size variants. You can see a photo of our unit's label here.
Popular Mouse Comparisons
The BenQ ZOWIE EC2-DW continues BenQ ZOWIE's venerable lineup of right-handed gaming mice that originally launched in 2009. It improves upon the last wireless iteration, the BenQ ZOWIE EC2-CW, with a new PixArt PAW3950 sensor, better mouse feet, lighter weight, and a higher maximum polling rate of 4000Hz. Otherwise, it has an identical shape and the same esports-focused ethos. Like other ZOWIE mice, it doesn't have any companion software, but you can change its settings on the mouse itself. This is useful for tournament play, where peripheral software may be banned. It also includes an 'Enhanced Receiver' which is required to reach polling rates above 1000Hz and is advertised to provide better wireless stability in noisy wireless environments, like LAN tournaments.
Its flagship price point puts it in competition with mice like Razer DeathAdder V3 Pro and the Logitech G PRO X SUPERLIGHT 2 DEX. While it generally can go shot-for-shot with those mice performance-wise, it has marginally worse click latency performance and a lower maximum polling rate. It's still an absolutely fantastic performer and very well suited for the highest levels of competitive play. It's also available in three different sizes, which gives it a leg up on the competition if you have smaller or larger hands.

The Logitech G PRO X SUPERLIGHT 2 DEX and the BenQ ZOWIE EC2-DW are wireless gaming mice with right-handed shapes. They have similar shapes, but the Logitech is slightly bigger and its hump has a different center hump with a more rounded curvature. The ZOWIE is available in small, medium, and large sizes, while the Logitech is only available in one size. While both mice have superb performance, the Logitech just edges out the ZOWIE with slightly better click latency and a higher 8000Hz polling rate.
The Razer DeathAdder V3 Pro and the BenQ ZOWIE EC2-DW are wireless gaming mice with right-handed shapes. The Razer is slightly bigger than the medium EC2 variant of the BenQ ZOWIE, but the latter is also available in small and large sizes. The two deliver very similar raw performance, but the Razer has marginally better click latency while the ZOWIE has marginally better sensor latency. Otherwise, the Razer uses the Synapse software to change mouse settings, while the ZOWIE doesn't have any companion software, and all its settings can be changed using buttons on the mouse itself.
The BenQ ZOWIE EC2-DW is the successor to the BenQ ZOWIE EC2-CW. While keeping the same shape, the DW improves on the CW with some small, yet meaningful changes that add up for a better overall experience. Namely, it's significantly lighter, has better mouse feet, and has a new sensor with a higher maximum polling rate of 4000Hz.
The BenQ ZOWIE EC2-DW and the Vaxee ZYGEN NP-01S Wireless (4K) are wireless gaming mice with right-handed shapes. The Vaxee's shape has a considerably lower profile than the ZOWIE, and its hump is flatter and further towards the rear. This gives it a smaller feel in-hand and allows for more flexibility for hybrid grip types. That said, the ZOWIE is significantly lighter than the Vaxee. The two have similar superb performance, but the Vaxee has marginally better click latency.
