The Zowie EC1 is a gaming mouse designed for competitive eSports players. With the latest technology and ergonomics, this rodent has some of the most advanced features on the market today. The newer PMW3360 sensor was included in the EC series by Zowie, demonstrating that perfection can be improved.

Zowie has brought basic ergonomics onto the micro-market for years, and the EC1-B series is no exception. The EC1-A and EC2-A mice were and continue to be very popular, but Zowie mouse fans have been clamoring for the newer PMW 3360 sensor to be included. This is now a reality thanks to the EC1-B and EC2-B. Zowie appears hell-bent on providing us with a variety of tournament-ready solutions that nearly always meet our performance expectations, which is fantastic. The EC-B series of ergonomic mice are available in two sizes: the EC1-B is the bigger of the two, while the EC2-B is a more medium-sized mouse that is smaller in every regard save the front depth.

The form of the EC-B series is inspired by the old but still famous Microsoft Intelli mouse that many of us used to possess (specifically the IME 3.0). The mice have a similar ergonomic design to the Razer Deathadder, but they don’t have the same high-quality polish to the touch, in my view. However, the quality of Zowie mouse resides behind the surface, which isn’t to say that the design’s understated simplicity isn’t something I’ve grown to like.


  • Simple Design — There are no frills here, yet it’s still lovely.
  • The ergonomic form makes it very comfortable.
  • Excellent tracking — This sensor is well acclaimed.
  • Durable — Sturdy, well-built mouse.
  • There is no software to install; just plug it in.


  • Material – After prolonged use, the material may become slick.

What is included in the box?

Zowie EC1 B Gaming Mouse

Zowie packaging exudes sophistication and seems to be designed cleanly and straightforwardly. The EC-B series comes in the same packaging as the EC-A series. The box is the same color as the mouse inside, and the front of the TV has a traditional outline of the featured mouse drawn on it. The packaging makes it apparent that Zowie is focused about function. You can tell since the box is just designed to store your future mouse and isn’t attempting to wow you with unique features or the newest technology.

We have the following items on the inside:

  • ECI-B mouse Zowie
  • Warranty/User Guide
  • 16 more feet

Size & Weight

Unlike other peripheral companies, Zowie developed the EC1-B and EC2-B mice to fit a wide range of hand sizes. Whether you have tiny or big (right) hands, the EC1 and EC2 have been built with comfort. They can also fit any play/grip style, with the smaller EC2 allowing for a fingertip grasp, but I’d suggest these mice for claw/palm play. The mouse’s back is the broadest, shrinking towards the center to provide a slight curvature for your thumb to rest on. It rises slightly in the center, creating a beautiful unnoticeable hump that lies well in most palms. As you’d anticipate from these fundamental ergonomic forms, the mouse bends slightly down to the significant buttons, giving it an exceptionally comfortable feel. Although I usually like a giant mouse (my hands are 1911), the EC series was different, and the EC2-B appeared to provide me with greater comfort when playing. It was due to the EC2-B’s smaller size and the fact that it is 4 grams lighter than the EC1 (94g).

With the improved EC1, Zowie has lost some weight. The EC1-B is now 3 grams lighter than its predecessor, and it’s 11 grams lighter than the Razer Deathadder. The mice’s weight distribution seemed highly balanced, which I believe makes a significant impact in-game since I wasn’t distracted by a top/bottom heavy mouse.

Shape & Texture

The EC series comes with a tried-and-true right-handed ergonomic design. Some people compare the series to the Microsoft Intellimouse, however it is a little chunkier. Nevertheless, the plan is comfortable, and Zowie has covered it in a smooth, slick plastic that is unexpectedly pleasant to the touch. This glossy coating may be excellent for grip if you don’t sweat too much, but if your hands get a bit damp, you might want to go for a mouse with a different textured surface, such as the Rival 600s rubber covering or the earlier EC-A series. In terms of ergonomics, the EC mice aren’t dissimilar to the Rival 310, but the EC mice have softer edges and gentle curves to accommodate a broader range of hand sizes.

Huang switches are used underneath the main primary buttons. They’re not horrible; they’re harder to push than Logitech switches, but they have a pleasant audible click and the actuation isn’t significant. The primary buttons are part of the mouse shell, which I don’t mind since they always click regardless of how high up my fingers are on the button. The switches, like the design, seem a little safe; I would have liked something a little lighter, but you won’t have any difficulty pushing them, and I didn’t do any inadvertent clicking.

The mouse wheel has been somewhat modified from the EC-A series. Zowie has removed the light-up scroll wheel that indicated what DPI level you were on, replacing it with a black tactile scroll wheel. If you regularly use the scroll wheel for jumping or other purposes, it’s worth mentioning that it’s rather noisy and may be bothersome. I didn’t notice since I only use the scroll for the odd weapon change or knife.

Two thumb buttons are provided for a few more in-game instructions, and they aren’t horrible. They have an outstanding firm feel to them and a gratifying auditory click when you click them. They’re slightly higher than your thumb’s normal position, but they’re not too tricky to get to. I didn’t have to modify my grip when pressing the thumb buttons on the bigger EC1-B. Still, I found it significantly more manageable on the EC2, making it the most comfortable choice fTwo buttons are located on the mouse’s underside. On the left, you may choose between the three preset polling rates of 125Hz, 500Hz, and 1000Hz. I usually set my mice at 1000Hz, but it’s nice to see that these parameters can now be altered quickly, as with the earlier EC series, you had to press various keys while plugging in the mouse to change the polling rate. In addition, a button to the right of the sensor provides you four color-coded choices to pick from, beginning with red (400 DPI) and ending with green (2000 DPI) (3200).


The Zowie EC-B series, like its predecessors, has rubber wires that aren’t braided. The wire is 2 meters long and did not drag or provide any significant resistance throughout my testing. These days, I don’t use a wired mouse without a bungee, and I think the Zowie cable is too thin and slippery, since none of my bungees will keep it in place as well as other mice. It’s not that the bungees didn’t keep the cable in place; the Camade from Zowie does, but I had to re-adjust after an evening of gaming since it had slid through.

Sensor & Performance

The PixArt 3310 sensor was used in the prior EC-A series, and owing to an early release issue with coil whining in the newer PMW3360 when it was adopted initially, users preferred the older EC-A mouse. The EC-B series has received a performance boost, which looks to have resolved some of the previous difficulties. With maximum tracking speeds of 7 meters per second, the Sensor was terrific. It functioned perfectly, ensuring that I wasn’t staring into the sky or at my feet following a quick response. Up to the blue DPI level, the sensor will give flawless tracking, and there will be no unmistakable smoothness (1600).

In CSGO, the mouse was fantastic, although it took a bit longer to get accustomed to than other ergonomic mice like the Razer Deathadder and the Logitech G403/603/703. The sensor worked well, but the EC1-B seemed a touch too bulky and heavy despite its modest weight. The EC2-B, on the other hand, was a lot easier to play with, and both mouse performed flawlessly in-game. Once I got acclimated to the EC-B series, snapping on a target was quick and accurate, and tracking heads in-game was quite simple. After just a few hours of usage, I understood why this form is so popular among recreational and professional gamers in the community. The mouse’s light ergonomic design and high-performance sensor translated well into whatever game I played, giving me a lot of trust in it.


The fact that Zowie mice are plug-and-play is a significant selling factor. If you’re still confused, the mouse don’t need any software or a connection to a cloud server! Yes, this implies no customization, but Zowie focuses on the most important aspects of their defense. Also, as previously said, you may still adjust your DPI, but you will have to choose one of the four choices below:

  • 400 DPI for red
  • 800 DPI = purple
  • 1600 DPI in blue
  • 3200 DPI = 3200 DPI = 3200 DPI = 3200 DPI


The overall build quality of the EC-B series was excellent; no excessive pressure revealed fragile plastic, and there was no rattling from the mouse after a thorough shake. The design is modest, yet this straightforward approach is refreshing, and the ergonomic form is a pleasure to handle. The primary buttons are delicate, but the other valuable buttons seem to be a little safe and afterthought; nonetheless, I don’t use the other buttons very much, so this didn’t concern me. It’s a barebones mouse, and at around £60/$60, you may ask why, but the Zowie EC-B series has a popular design, a fantastic sensor, and is, of course, plug and play, so we can understand why the EC-B is so popular.
