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

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.

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 :( )

This brand is getting some hype for being value priced competition without being garbage. I'll agree with that. At work I use a Logitech MX Ergo that I've had for at least 7 years. I've had zero issues with it and it has been extremely reliable. It was also $75 when I bought it. I wanted one for home too and found this ProtoArc for half the price and some good reviews. Here's how the ProtoArc compares (and I'll use my MX Ergo as a comparison tool). The overall size and shape is very comparable to the Logitech. It's a bit different, of course, but it's an easy transition from one to the other. Both are excellent for ergonomics. Buttons on the ProtoArc are just fine. They're quiet and work well. Both it and the MX Ergo have different features. The Ergo has a customizable thumb button (default is 'precision mode') and a horizontal tilt/scroll feature on the wheel. Makes navigating spreadsheets and graphic arts documents really easy. The ProtoArc doesn't have either of those, but it does have two buttons in the thumb position that control sensitivity (so you still have a "precision mode" technically), and there is no tilt wheel for horizontal scrolling. Both have buttons right below the wheel to change input mode, and both have two small buttons to the left of the main left button. These are set on the ProtoArc for I believe forward and back (not at home so I can't verify), while all of the buttons on the MX Ergo are customizable with Logitech software. The ball on both mice are good and similar in size. The bearings on the Logitech are just better, the ProtoArc isn't as smooth, but it's not bad either. You can use the MX Ergo while charging, and if you use the Logitech software, you can get pop-ups notifying when the battery is low. The ProtoArc just dies and quits working, and will not work again until the battery reaches a certain charge level; I have never got it work with a cable immediately after it dies. The batteries on both mice are extremely long lasting. So...should you buy one? If you have never used a trackball and are interested...this is a great entry point to try one out, and it's a good product on top of that. It feels solid under the hand, and has had zero issues. I wouldn't trade my MX Ergo for it, but my MX died and someone gifted me a ProtoArc as a replacement...I'd rock it.

Not often I comment here, but this mouse is excellent. Can't count the number of rollerball mouse's I've had, including Logitech and they have all been lousy. Keeping my fingers crossed on this one but so far so good. Very smooth, great ergonomics adjusting in two directions. Easy to use whether you chose Bluetooth or wireless. Holds a charge for a really great period of time, that of course will depend on the application you use it for. Excellent scroll speed. The size is slightly larger than others I've had but I actually find I like it better.

Muy cómodo. Excelente relación costo / beneficio. El track Ball es súper suave, incluso más que el Ergo MX. Los botones requieren de poca presión para activarse. Funciona muy bien.

Nice stylish black trackball with (I choose) a red ball. Luckily no fancy LED lights, and connects to PC and MAC. Great!! What could be improved is a small storage area in the trackball for the dongle (wifi/bluetooth)

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.

devo dire che ho sempre comprato logitech pensando che era il migliore, ma mi sbagliavo. questo oltre avere più funzioni è nettamente superiore come qualità e velocità del puntatore. è meraviglioso e più bello complimenti al costruttore.
