My wife and I have both been using the Logitech M570 trackball (and it's various ancestors) for decades. Each and every single one would typically last approximately 2.5-3 years, at which point the left mouse button would begin to add in random additional clicks when used. This happened again, last week.
Normally, I avoid off-brand products like the plague. I have rarely had even acceptable experiences with them - generally, the experiences were terrible. Amazon's return policy, however, offers me a bit of flexibility when it comes to product selection. With this in mind, when I happened to see this item, sporting a 20% discount (bringing the price down to $39.99), I figured, "Why not?" I am SO glad I did!
This trackball is excellent! Construction, battery life (so far), setup - all were exemplary. If you are in the market for a new/replacement trackball, I highly recommend you give this one a shot. You will be pleasantly surprised.
Pros:
Quality construction - the plastic feels solid and the trackball as a whole has a nice "heft" to it.
No extraneous software needed - the trackball works as a plug and play mouse. The RGB ring around the ball is controlled via a 5-setting push-button (4 color patterns + Off).
Rechargeable built-in battery (USB-C) - No scouring the junk drawer for AA or AAA batteries.
Battery Life - I've been using mine heavily for four days and still have 43% charge remaining.
Connectivity - This trackball can be connected to a max of three devices at a time; one via the (included) 2.4 GHz receiver and two via Bluetooth. Switch between devices with the touch of a button.
Comfort - trackball can be used in a flat position or at a 20-ish degree tilt to the right.
CONS:
No direct control of the RGB ring: there are 4 color patterns and off - that's it. While this doesn't bother me, it may be an issue for some users.
The scroll wheel has a very tight, crisp movement between clicks. I find this perfect, my wife does not.

Good competitor to the MX Ergo
I've been using trackball Mice for CAD work for years and came to rely on a Logitech MX Ergo for my main workstation use. The version I have is the Ergo Plus with the additional angle platform (adds another 20 degrees of tilt). The Logitech suddenly became erratic, and would not track properly across the screen. Sensor cleaning would not fix it and I purchased this ProtoArc Trackball to try out and see if it was a system problem or a failure of the MX Ergo. At about half the price of the MX Ergo I seemed like a low risk try. I use the Bluetooth connection and the ProtoArc connected easily and worked right out of the gate. No erratic movement and it tracks nice and smooth. The trackball feels identical to the MX Ergo. On the plus side, the buttons on the ProtoArc are superior to the Logitech and have a really nice feel. They have a subtle pop feel and less of sharp click feel. The RGB lighting around the ball is nice. All the other functions seem to match well with the similar MX Ergo. The biggest disappointment is the scroll wheel. Where the buttons on the ProtoArc feel superior to the Logitech, the scroll wheel feels very cheap in comparison and has an inconsistent sound that seems to rattle at times. The push to activate middle mouse button on the wheel is quite stiff. I use a Spaceball for spinning CAD models, or otherwise this would have been a deal breaker. Beware if you use applications that require long press and hold of the middle button. I knocked it down a star for this. The other item it is lacking is the optional riser of the MX Ergo Plus. However, it does fit well enough on the Logitech riser to work, and now it feels pretty much equivalent to the Logitech for my use (see picture). Overall it is a keeper despite the scroll wheel. Too bad as ProtoArc was close to a better version of the MX Ergo.

Pretty good budget alternative to MX Ergo, but with a ridiculously unnecessary RGB light.

First impressions are generally positive, and the feel is very familiar to me as the size and shape is nearly identical to the Logitech MX Ergo I was using previously. The tilt angle feels nearly identical, and even the ball is exactly the same size and they can actually be swapped between the EM01 and MX Ergo.
Bluetooth pairing was simple and quick, and it arrived with 91% charge out of the box so I could start using it right away. The tracking feels nice and accurate, and cycling through the sensitivity settings is simple and convenient with the dedicated thumb button.
The overall fit and finish isn't quite as good as the MX Ergo, but at less than half the price that seems like a reasonable tradeoff. The EM01 feels noticeably lighter than the MX Ergo, and definitely has more of a hollow feeling to it, but not offensively bad. At least with the EM01 the outside surface is all plastic so there wont be any unsightly rubber coating peeling like I had with both of my previous MX Ergo mice.
The buttons are noticeably quieter than the MX Ergo, but I suspect largely because they feel a little mushy in direct comparison and lack most of the tactile "clicky" feeling. Again, not terrible, but just feels slightly worse directly comparing the two.
The biggest issue I initially had was the edges of the plasic pieces had very sharp feeling edges that made it quite uncomfortable in my hand during use. I was able to correct this by burnishing the edges with another piece of plastic, just to take a bit of the sharpness off. I ended up using a plastic keycap puller I had laying around to do this, but any plastic of similar hardness to the mouse would work, just running it along the edges a few times.
Lastly... RGB... on a trackball? Completely unnecessary, but luckily its easy to turn off to save the battery, so thats how mine will stay.
Overall, I do think the EM01 is a suitable alternative to the MX Ergo, especially if you're sick of dealing with the gross, peeling rubber coating on the Logitech after a year or two of use.
