Review: Good size trackball; very easy use with either hand - Great trackball. Easy to connect; just plug the dongle in, and it's good to go. Really good size of trackball allows me to use three fingers to navigate precisely with my non-dominant hand. Comfortable to use from the couch too. The buttons click nicely and the scroll wheel works well. It's definitely a little bit pricey, but definitely worth it to be able to rest my injured dominant hand but still be able to enjoy good precision when using my home PC. The ball comes out easily to clean, so I wouldn't want to take this loose in my bag into the office, but that isn't really a consideration for me since I've switched this one out for the Orbit Fusion, which I'll take to work instead.
Review: Good upgrade from old trackball - I had the Kensington orbit with scroll wheel previously, which stopped working after 18 months. Kensington is willing to send out a replacement which will take 2 weeks which is a long wait. Decided to get the expert as an upgrade as I cant wait that long for a mouse. The expert is a much bigger unit and the ball is probably double the size. Overall it you feel it is a better product and has 4 programmable buttons instead of the normal 2. Ironically because of the size of the ball and the placement of the buttons. I dont have the top 2 buttons as left and right click. I have bottom left as left click and top right as right click. There is one slight niggle the scroll wheel is a little too close to the right buttons so sometimes you nudge the right buttons when using the scroll wheel. If you are on a budget the orbit is fine but if you use the mouse a lot, the expert maybe worth considering

## Questions & Answers

**Q: Does the scroll ring have notches as it spins, or is it free moving? i’m looking for something to allow precision zoom/pan control in cad.**
A: There are notches on the ring, but it is smooth.  I use this and the other mouse for AutoCAD Electrical 2023 and have to say the other is the better choice.  It is more expensive, but way way more practical when you need to press a mouse button AND move the wheel.  I also tweaked the CAD zoom factor.  I now find any other mouse just does not perform the same way.  I don't know what the part number of the other mouse is (on a different PC), but it is the big square one.  The ball is about the size of a snooker ball and the cursor does not move when you take your hand away.

**Q: Will it work with windows 10?**
A: I don't have the wireless model, mine is wired which is an older model but it does work with windows 10, so I would expect the wireless model you are interested in to work with windows 10 also.

**Q: 20.1 x 15.8 x 8.5 cm is this size accurate?**
A: These sizes are for a wired trackball not the wireless in pictured

**Q: Is this compatible with chromebook**
A: Hi,

Thanks for the query.

There would be no problem at all with using this with a Chromebook. These are ready to use any external mouse when connected. 

Kind Regards,
Ebuyer Support

### ⭐⭐⭐⭐ Ergonomic, but less accurate than a mouse
*by R***R on 15 January 2022*

Pros: Truly ergonomic. Very fast to get from one corner to another corner of a large screen. You don't need to move it around like a mouse. Hand and wrist practically unaffected, no pain whatsoever. Easy to clean. It looks very cool. Cons: Considerably more difficult to click onto a specific point of the screen. Not a problem if you need to perform such a task occasionally, but may feel tiring if you need to do it regularly. e.g., you need to click many times into tick boxes. Somewhat more difficult to scroll. Quite large. Conclusion: Will it replace a mouse? Probably not. Will a mouse replace it? Definitely not, it is a completely different type of "animal", but you need to get used to it.
