ProtoArc Wireless Trackball Mouse, EM01 NL Ergonomic Bluetooth Rollerball Thumb Rechargeable Computer Laptop Mouse, Adjustable Angle & 3 Device Connection for PC, Mac, Windows-Gray Ball

for Multi-Device Power Users with Incredible Battery Life and Ergonomics
Incredible Battery Life and ErgonomicsI always like to give a product at least three months of consistent use before writing a review, so I can speak to its long-term performance. After using this ProtoArc trackball daily, I can say it’s a fantastic piece of equipment, especially for anyone juggling multiple computers. The ergonomic design and adjustable angle have been a lifesaver for my wrist during long work sessions.Functionally, this mouse has been a reliable powerhouse. The trackball is smooth, the connection is flawless, and switching between my devices is seamless. But the battery life is what truly blows me away. In the entire three months I’ve been using it, I have only had to charge it once.My long-term experience has been overwhelmingly positive. If you want a comfortable, reliable mouse with a battery that lasts forever and streamlines a multi-device workflow, this is an excellent investment.

Lightweight plastic. Tilt is on a hinge, easy to charge.
I have hands with damage from arthritis so moving a mouse is a literal pain. I have used trackballs for over 20 years. When I tried one with a tilt, I was hooked. I like to have a mouse at every computer. A new crafting machine needed a computer so I needed another mouse. Rather than spending a lot of money to get another Logitech, I thought I would try this. It is a good deal and will do the job I need it to do,Cheaper plastic, the hinge that gives the tilt could break if the user is not careful. Trackball Scroll speed can easily be set from slow to super fast. Super fast might be good for gaming but not so great for everyday work. The back/forward buttons are in an inconvenient place. I would have switched them with the mouse speed buttons. Scroll wheel speed is okay. Disappointed that you cannot click with the scroll wheel.I have smaller hands and this fit well. Once I got the speed set for how I am using this mouse its functionality is just fine. Battery life seems to be okay, It is easy to recharge it. The price was right for me to try it. Is it my Ergo MX, no but this is a fraction of the Logitech.This connected easily to my android tablets and phones, It also easily paired with my Windows 10 and 11 devices. This will not replace my work trackballs but they will be the go-to in my crafting room.

Bought this just to spite Logitech, and I’m pretty happy
After having spent $70 on the fancy Logitech MX Ergo trackball, my left button started failing after 3.5 years. I certainly didn’t want to spend another $70 on a trackball that doesn’t support bluetooth and charges with a micro-USB port.Then I came across the ProtoArc, an obvious clone of the Logitech MX Ergo but with all the features I want. It can connect with both bluetooth and the included dongle, charges through USBC, has an up and down button for tracking speed, a larger 900mah battery (vs 500mah on the Ergo) and cost half the price of the MX Ergo.There doesn’t seem to be any compromise in quality. The trackball is very smooth, and the build quality is solid. They also put thought into their packaging to boot. Oh, and the tilt plate on the bottom of the trackball attaches to the whole unit so it doesn’t come off. It’s a small detail but I definitely like that more. There is one slight complaint however, it’s that the scroll wheel is harder to spin, making my finger more tired after scrolling a lot. Hopefully I can just oil the scroll wheel or something to make it spin easier.I’ve used Logitech trackball for the past 25 years, started with their wired version to the MX570 for both home and the office, followed by the MX Ergo in 2020. Logitech seems to reserve their most expensive products for bluetooth support and for the trackballs there isn’t even an option with the premium price. I was forced to use my Macbook that has no USB-A port with an adapter just to have the dongle plugged in. Makes you forget it’s the year 2024.I’m glad that ProtoArc stepped up to the plate and offered a great trackball. I’ll now keep an eye on what else they offer. Hopefully a keyboard that rivals my Logi K750.

Excellent Mouse Overall.
Excellent Mouse. No lag, and very adjustable. Build quality is very good. Rechargeable battery is great. Long usage time between charges.

Just amazing. Before switching to Protarc, I was using Logitech ergo m575. I switched to earlier model of Protarc, and I was so happy with it until it broke recently. ( Idid not go to warranty route because it was kinda my fault that it broke- when trying to clean it, I pulled so hard that a button broke). So naturally I went to Amazon to order the exact same one, but I could not find the earlier model, so gave this one a try. And let me say- it is AMAZING. I loved how Protarc improved their designs significantly. For example, in the earlier version I was using, switch bottons were at the bottom. I like how this one had those on the top. Really liked the angle adjustability. I am using a computer for more than 12+ a day, so it is really important for me that I have a comfortable mouse. When I first switched to trackball, it was because I was getting constant pain on my hands from using classic mouses, and when I first switched to trackball; I got weirded out at first; but only took me a couple of days to get used to it, and now I cannot switch. Overall, great product; very affordable for such a high quality, so much better in design, and in quality than more expensive products. It comes in a quality box, with very simple instructions, which adds an extra layer of satisfaction. I generally do not make a lot of product reviews for my Amazon purchases, and even if I do, it is never this long, but I genuinely wanted to take my time today to thank the seller for such a good product. 10/10 would recommend

I was looking for a good vertical mouse to ease the strain on my shoulder. This mouse fit the bill perfectly and I love the fact that you dont have to move it around, it just stays perfectly in place next to my keyboard and I never have to worry about running out of space to move the cursor. I have a standard (non-trackball) vertical mouse at work that is worth over twice as much as this one, but I like this trackball mouse a lot more. One of the best home office purchases I have made. Thanks.
