## Description

Product description ProtoArc EM01 NL Wireless Trackball Mouse EM01 NL wireless trackball mouse Bluetooth & 2.4G Wireless Switch freely between Android, tablet and Mac with just one button 900mAh Large Battery Capacity Easily charge the mouse with the included usb c charging cable anytime anywhere EM01 NL Trackball cleaning video Keep Your Trackball Rolling Smoothly Is your trackball feeling sticky, jumpy, or less responsive? Over time, dust, oil, and dead skin cells build up inside the mechanism, causing the ball to drag or the cursor to skip. In this video, we’ll show you how to give it a proper clean. Regular maintenance restores that silky-smooth glide, ensures precise cursor control, and extends the life of your device. A few minutes of care makes all the difference! Warm Tips for EM01 NL Wireless Trackball Mouse The trackball mouse offers a distinctly different feel compared to traditional mice and may require some time to get used to. For first-time users, we recommend starting at 200/400 DPI and adjusting only once you feel comfortable. This product does not support horizontal scrolling (tilt function). This product is not recommended for tasks that demand extremely fine cursor control or high precision, such as image editing or CAD design. For users with smaller hands (measured less than 17.5 cm from the base of the palm to the center), the size of this product may be too large to hold comfortably. Please note that using a USB charging cable purchased separately may not charge the device. Always use the included USB cable. All the buttons are non-programmable and the backward forward buttons are not compatible with Mac OS system.

Review: Effortless and Quality Mouse - A Definite Buy (Recommend Buying) - A definite buy if you are looking for a trackball mouse. Build quality is pretty good and it feels effortless to use the mouse. Trackball movements/motions are very very smooth. Very smooth scroll wheel. Left/Right click buttons require perfect amount of very light pressure to work, therefore the fingers wouldn't get tired after continuous use and same for the forward/back button. Click sounds while using the mouse are very subtle and just loud enough for you to hear the action. The DPI levels (the cursor speed) buttons have 5 levels that are perfectly spaced for varied needs. Size of the mouse and curves/arcs on the mouse are well designed and thought of for ergonomics and comfort and not to forget the 20 degree angle plate at the bottom of the mouse allows you to change the angle of the mouse, is a big plus. It can connect to 3 devices and I had no issues connecting it via Bluetooth. Only drawback is there is no storage for USB receiver/dongle on the mouse and it has to be stored separately, I would recommend ProtoArc to improve on this aspect. Another suggestion would be to provide the ability to customize the back/forward buttons to actions that user prefers. I also own a Logitech trackball mouse but after using ProtoArc's effortless mouse, I am NOT going back to Logitech.
Review: Very Very Premium, Very Very Good - I have to say almost 6 days coming up on a year after buying this mouse, its perfect. Its funny cause when i bought this, i didn't really sift its specs thoroughly, didn't know physically moving the mouse didn't move the cursor, I just bought it because it looked good & it shipped fast. First off, the build quality is amazing, it feels and weighs very premium. love the fact that I can just recharge it with usb c. when I first got it, it took about 4 hours to get used to it because before it, the mouse i had was regular, so hand positioning was a bit awkward at first but after those hours i loved it. Never going back. Its very smooth and the scrolling is so good and easy to adjust. love that. One thing that's weird about it (or weird about me) is that u can use this while sitting in your chair (place it on the arms rest), standing up, on your lap, or laying down in your bed for tv (i use a projector). Its comfortable in every way. Although i said it took 4 hours to get used to, gaming took a bit longer, but over time it becomes way easier and honestly in my opinion, more convenient than a regular mouse. Reason why I say this is because for some people like me, our table may not have a lot of room to move the mouse, but with the rollerball, the ease of it is crazy. The battery lasts so long, I just charge it for the sake of seeing it charged, never for the sake of "its almost dead, or it died, lemme go charge it", if that makes sense. And the smooth connectivity is awesome, switches between devices like its nothing, the distance i can use it at is very good and I love the number-lights thing. Once you buy this mouse, you wont believe the quality you got for the price (compared to others). If the rollerball gets a bit slow or choppy, all I have to do is use my thumb and forcefully roll the ball until it feels smooth again, which i rarely have to do but its a quick fix, no extra steps. Overall, it feels awesome, performs awesome, and its aesthetic is awesome.

## Features

- ERGONOMIC DESIGN for MORE COMFORT: Unique adjustable hinge allows you to customize the trackball angle from 0 to 20 degrees according to your needs, ensuring a more natural, comfortable hand position for all-day comfort
- Precise Thumb Mouse: ProtoArc trackball mouse provides accurate and smooth tracking, allowing for easy navigation through documents and web pages. You no longer need to move your arm for the movement of the cursor. Your thumb will control the cursor instead via the trackball. It will effectively reduce fatigue and strain on your wrist and arm. More productive in the narrow space, such as the messy desktop, couch, bed etc. Note: this trackball mouse is not an ordinary traditional mouse.
- Bluetooth & 2.4 G Wireless Connection: PLUG and PLAY. This trackball mouse has triple connection modes. You can control three devices at the same time, switch freely between PC, laptop and iPad with just one button to improve your efficiency. Compatible with Windows, Android, Mac OS PC Laptop Desktop etc
- Rechargeable & Adjustable DPI: The bluetooth Trackball Mouse built-in rechargeable lithium battery. No need to change batteries. Please remember to turn it off if you do not use it for a long time. 5 DPI levels (200/400/800/1200/1600) allows you to change the cursor sensitivity easily and track more smoothly
- Quiet Clicking: Smooth frosted surface and quiet clicks can bring a better user experience and free your worry about bothering others and keep you stay focused while working. Note: The middle scroll wheel is not silent. All the buttons are non-programmable and the back forward buttons are not compatible with Mac OS system
- After using the trackball for a period of time, please clean the trackball and the three white rollers inside the hole to ensure that the trackball is always smooth. Note: When the computer is just started or a large application is running, it may also cause the trackball to not run smoothly
- Warm Tips: Since it takes a learning curve to get used to the control method when using our trackball mouse for the first time, it may cause inconvenience to your mouse grip, you can experiment with different hand positions to find what is most comfortable for you. We recommend that you take 1-2 weeks to get used to it, as many users find that it will help reduce the pressure and pain on your wrist caused by long-term use of the mouse and improve comfort

### ⭐⭐⭐⭐⭐ The Real Value Buy over the Logi MX ERGO+
*by E***S on December 31, 2025*

Great value for the price, it definitely competes with the Logi(tec) MX EGRO Plus, it has all the same or simmilar features (from what I have used it for) - same buttons, sensitivity button, scroll buttons, wrist angle adjustment plate, usb C connector/charging port, thumb movement is good and feels similar, and it has one improvement: you can connect it to 3 different devices (vs 2 w the logi). Trackball Tangent: This is a great trackball mouse for those who know they like them, and for those looking to try one, this is a good buy, if you have never used one, you should expect to spend a couple hours getting used to it, and probably a month to get fully comfortable. Benefit: If you use a laptop or tv for your computer needs, a track ball is great because you dont need a sturdy table, you can hold it on the couch or even your leg, thus allowing for mouse, or keyboard & mouse in far more situations/locations. Note: I paid $38.69, and it looks to be even cheaper ($29) at the moment, and I thought I got a great deal. Note 2: If they are close in price when you are shopping, get the purple or yellow/gold ball version, those have proper amounts of flair (I messed up and got the grey version :( )
